Hook Ups

Hey Tyga, someone has a message for you ... stay away from our high schoolers!

Hanksy -- a self-proclaimed cross between Banksy and Tom Hanks -- skulked in the 'hood around Calabasas High ... and other places around L.A. ... to plaster signs warning that Tyga might be on the prowl.

Obviously the art was inspired by Tyga's relationship with 17-year-old Kylie Jenner, who does not attend that school or any high school for that matter.

Timothy V. Murphy has no problem with kissing and telling… at least when it involves the iconic Jane Fonda and her ageless mouth.

Our photog caught up with the "Sons of Anarchy" star to get the deets on his intimate scene with Jane on her new Netflix show, "Grace and Frankie."

Yeah, she's 77, but Timothy couldn’t wait to tell us why he'd put Jane's lips -- and tongue -- up against any chick in the biz.

You know Bradley Cooper's getting serious when he parades a lady friend around town, instead of hiding her from photogs -- and supermodel Irina Shayk is now firmly in that category after a night out in London.

The really, REALLY good-looking pair were all smiles Monday night, and after hanging with friends ... they climbed into a cab together ... still giddy.

BTW, Bradley and the Russian top model were hanging at Novikov Restaurant, known for its Wagyu tacos, Hamachi carpaccio and generally drawing smoking hot customers in skimpy dresses.

Candace Cameron-Bure & Andrea Barber could have ended up with Knight or Wahlberg as their last names -- but freakin' lawyers came between the "Full House" duo and the New Kids on the Block.

D.J. and Kimmy Gibbler caught the NKOTB show Saturday in L.A. ... and while they never say if they ever hooked up with Jordan, Donnie or any of the others ... it sounds like they would have if not for some legal red tape.

More importantly, it sounds like Andrea had a little vino ... 'cause she was giggling like a teenager.

Girls night out isn't for BF's ... unless you're Russell Wilson ... 'cause TMZ Sports has learned the Seahawks QB surprised Ciara at a fancy steakhouse ... and she could not have been happier.

Ciara and two girlfriends were having dinner Saturday night at The Palm -- one of D.C.'s best restaurants -- drinking wine and eating crab ... when Wilson unexpectedly arrived during dinner.

The restaurant G.M. Mike Melore tells us ... "Ciara was shocked to see him. She said she didn't know he was coming, but she was super happy he was there."

And, when you're rich and famous ... you can stay as late as you want.

"We normally close around 10:30, but we stayed open late for them, until 1:30 AM," Melore says.

"They were extremely nice and humble. They took pictures with every staff member that asked before they left."

Amber Rose ended her Mother's Day celebration by calling someone daddy ... we're betting.

Amber snuggled up to her latest BF, Machine Gun Kelly, as they stepped out in NYC to party with friends at Cafe Felix.

Muva was noticeably low key on social media all Sunday -- so she was probably hanging with her 2-year-old son, Sebastian. But every Mother deserves a little me time, and it looks like Amber got hers.

Whole lotta changes going on in the life of Ryan Seacrest -- his gig at "American Idol" is ending, he seems to have found a new hot chick with whom to hang out.

Seacrest was spotted Saturday night leaving Il Piccolino in West Hollywood with a new mystery blazin' hot brunette. After breaking up with model Shayna Taylor last December, Seacrest had been seen out with a different model, Renee Hall, but that appears to be over.

Justin Bieber got on stage Saturday night ... a big deal because it's his first full concert performance in 2 years ... and guess who closed the show?

Justin took the stage Saturday at KIIS FM's Wango Tango, 2015 in Carson, CA. Fans went crazy for 4 hours before Bieber took the stage at 8:30 PM.

Kanye closed the show, so it wasn't surprising his mother-in-law Kris Jenner was in the audience. A little surprising ... she was sitting next to Big Sean, who had beef with Bieber over the whole Ariana Grande hugging thing.

Taylor Swift was shakin' it off in a big way as BF Calvin Harris took the stage at Wango Tango.

Taylor showed up Saturday at KIIS FM's Carson, CA event and stood on the sidelines, dancing her face off.

Taylor was there with the Haim sisters, the chicks who introduced her to the famed DJ.

Liam Payne and Louis Tomlinson got a couple of fabulous parting gifts Friday night from an L.A. club ... 2 more than agreeable chicks.

Two of the remaining members of One Direction were leaving Project L.A. when their bodyguards tried a feeble diversionary tactic ... Liam, Louis and the 2 women all left the club separately, but their cover was clearly blown because they all ended up in the same car.

Drake and Rihanna ended up at the same club Friday night, and it's apparent from the video there are no hard feelings between the two.

They each came separately to the VIP Room in NYC, saw each other and greeted each other warmly.

It's a brief encounter, but it's easy to see there's no bitterness. You'll recall the 2 had hooked up and it triggered a massive brawl between Drake's people and Chris' posse at W.i.P nightclub in the Big Apple.

Selena Gomez and Miranda Kerr came face-to-face and cheek-to-cheek ... and given their history, it could have been a tad AWWK-WARD.

Quick check of the scorecard -- Gomez and Kerr allegedly hooked up with each other's exes ... Justin Bieber and Orlando Bloom ... which allegedly led to Orlando taking a swing at Justin in Ibiza last summer. They all deny the allegations.

Now cut to Wednesday in Palm Springs where Miranda and Selena seemed totally cool with each other at a Louis Vuitton event. Sure, they could be faking it ... but we've seen them hang before -- at another LV gathering.

Tyga is now defiant about his relationship with 17-year-old Kylie Jenner ... he doesn't care about the laws prohibiting adults from having sex with minors, and the reality is ... unless someone complains, neither do the cops.

Tyga is telling friends, as far as he's concerned Kylie is more mature than most adults. She's a millionaire who runs a company and even owns her own home.

The rapper won't squarely say if he's intimate with Kylie, but it's not hard to read between the lines. He says he "doesn't give a f*** about what the law says." He thinks age is relative, and there's nothing "morally wrong" with a mature 17-year-old dating a 25-year-old.

Fact is ... the cops may be on his side. Law enforcement sources tell us they won't investigate statutory rape involving a 17-year-old unless someone complains, even if the relationship is widely reported. And they say, so far no one has complained.

Hip-hop producer Mally Mall must be bored with love triangles -- the "Love & Hip Hop: Hollywood" star is breaking up with Nikki Mudarris again, but this time THREE other chicks are involved.

Mall and Nikki are known to be on-again/off-again (a recurring theme from Season 1) and their relationship status was set to OFF after a blowup over a Las Vegas fight weekend party.

According to our sources, the couple was supposed to host a Mayweather/Pacquiao party at a rented house in town, but Mally showed up with three chicks that weren't Nikki ... and she didn't show up at all.

Season 2 is just writing itself.

Katharine McPhee's estranged husband gave her a hand Tuesday ... a very gentle hand.

It's a stark contrast to her split with Nick Cokas, which allegedly came after Katharine was photographed sucking face with her "Smash" director Michael Morris. Katharine claimed in the documents she was already separated from Nick, but he says they were still together.

But things change ... or do they? A source close to Katharine insists Katharine and Nick had a friendly business breakfast in West Hollywood. He's still involved in her music stuff.

Tyga refuses to let anyone tell him where he can bring his underage GF, Kylie Jenner ... so he ignored a college's request to keep her off campus during his concert ... TMZ has learned.

Tyga performed at Cal State Fullerton's Spring Concert this past Saturday, and according to our sources ... concert organizers told him he should NOT bring 17-year-old Kylie to the show.

We're told not only did the university find their relationship questionable, but the show was 18 and older. Tyga must have known he had the school by the balls -- they couldn't afford to bring in another act at the last minute -- because he went ahead and brought her anyway.

While he was performing ... she was chilling at a table full of chicken wings and other appetizers -- which we're told Tyga suddenly demanded when he arrived ... an hour late.

Organizers didn't want to risk him bailing completely ...so, we're told they just let it go.

Kylie's presence didn't go unnoticed by the students, with one tweeting, "CSUF said guests must be 18 or over to enter spring concert but Tyga brought Kylie as his guest."

As we reported ... Tyga ran into the same situation during a gig in November, but opted to boycott the club. The couple put their age issues aside Monday as they flew out of LAX -- airlines don't care if he travels with a minor.
