Hot Mamas

67-year-old Cher is still super proud of her boobs ... and proved it by sportin' a pair of nipple pasties this week at a concert in Boston.

Cher -- who also rocked a pink wig, pink lip gloss at her Dressed to Kill tour -- seemed extra perky that night ... and also broke out her old low-plunging black onsie from her "If I Could Turn Back Time" video.

As for the nipple pasties ... one question -- doesn't it hurt to take those things off??

Bundchen's bum is undefeated against thongs, so Gisele had to ...

RELEASE THE KRAKEN!

Some people glam it up for a trip to LAX, knowing paparazzi will be there ready to snap their photo.

Britney Spears is not one of those people.

It's her prerogative.

Don't expect Megan Fox to wear mom jeans after popping out another kid last month ... because she already lost all the baby weight -- in 5 freaking weeks!

Fox ran some errands Friday in Los Angeles with her other son Noah -- after giving birth to Bodhi Ransom in February -- and one thing is clear, girl was looking GOOD.

Chris Hemsworth and his wife are at Cedars Sinai Medical Center right now giving birth to twins ... TMZ has learned.

It's ultra-high security in their hospital suite ... we're told 2 security guards are standing at the door. Chris is strolling the hallway and is being escorted with a guard.

Chris and his wife Elsa Pataky already have one baby -- India Rose Hemsworth who is now 22 months old. She's about to have a couple new siblings.

It's the question millions of couples ask themselves before entering the delivery room -- and now Jay Cutler's in the same boat -- does your wife want you to see EVERYTHING when she's giving birth?

Fortunately for the Chicago Bears QB -- he won't have to guess ... 'cause his wife Kristin Cavallari was out in NYC today and told us.

Atlanta Falcons lineman Kroy Biermann might not be ready to retire yet ... but his balls are -- 'cause the defensive end tells TMZ Sports his baby makin' days are officially over.

Kroy and his reality superstar wife Kim Zolciak were leaving LaGuardia Airport in NY this weekend without their 4-month old twins ... the 5th and 6th kids in the Biermann family.

Of course, we had to ask if the couple was planning on poppin' out a lucky #7 ... but Kroy made it crystal clear six is plenty enough.

Just like most plus size girls who lose a ton of weight ... Jennifer Hudson is dumping her main squeeze -- Weight Watchers.

Hudson says her time with the diet company has been life changing ... a total understatement ... she went from a size 16 to 6, losing 80 lbs, using the product -- and got pretty damn hot in the process.

J Hud linked up with W.W. in 2010 after giving birth the year before.

Company honchos say they assume she will continue using their products.

It sure seems to work better than pizza.

"Basketball Wives" star Jackie Christie thinks pregnant women with ornery cats should kill the kitties by hanging, choking or other means if necessary.

It's pretty shocking ... our photog asked Jackie (in the dark blouse) and her friend, Sundy Carter (who appeared in "Bringing Down the House" and "Soul Plane") about what a pregnant woman should do with a temperamental cat.

Both women have no mercy for fearless felines. In fact, Jackie actually thinks cats can suck the soul out of babies and even kill them.

Ciara's baby won't be born for another month ... but she's already taking steps to make sure the kid appreciates the world of animals ... so she dropped $20K on an animal-themed nursery.

Our baby spies say Ciara and her fiance Future dared to shop at pricey Petit Tresor in L.A. ... dropping $1,800 on an 8-foot stuffed giraffe. They spent the balance on other stuffed animals, lion book ends and art work.

Ciara's been on a spending spree ... she was recently out shopping at another high end baby store with Kim Kardashian.

FYI - A REAL safari costs around $1,000 a day.

Miami Dolphins linebacker Philip Wheeler says his girlfriend is being unfairly attacked over a picture showing her breast-feeding their son ... and now he's calling for people to stop the boob hate, asap.

Wheeler's GF is model Ashley Nicole -- who recently posted a photo showing her son latched on to her right breast inside of their home. She included the caption, "Was on the way out the door but then mommy duty called... Everything stops for him! #breastisbest #natureisbeautiful."

Problem is ... not everyone felt the same way -- and social media erupted with people trashing Nicole for posting the pic in the first place.

TMZ Sports spoke to Wheeler ... who says, "I wish everybody would just leave it alone" ... adding, "She's a model. She takes pictures for a living."

Wheeler pointed out that Gisele posted a breast-feeding pic back in December -- and was widely praised for it -- and doesn't understand why his GF isn't getting the same love.

As for the pic, it's still posted on Ashley's Instagram page -- and we're told she has no plans to take it down.

Heidi Klum's not afraid of a little PDA -- donating some fresh spit to her young art dealer boyfriend Saturday night at a Hollywood nightclub ... in the middle of the crowded dance floor ... and TMZ has obtained photos.

The DFMO (dance floor make out) went down at 1 OAK -- Klum grabbed 27-year-old Vito Schnabel's face and passionately kissed him in front of everyone.

She looks really into it. Vito looks like a prom virgin.

Then again, he's the one dating a supermodel.

It's a modern day good vs. evil.

Here's a saintly looking 41-year-old Sofia Vergara posing in a couture toga party inspired gown (left) with a sinfully lacy 28-year-old Irina Shayk (right) at an Oscars after party last night.

Michael Strahan's fiancee proved he's a lucky man Wednesday night at a karaoke bar in Malibu -- by showing off her serious ass-shaking skills and putting young hotties to shame.

Nicole Murphy popped her booty to "Pony" by Ginuwine at Cafe Habana with co-stars Shamika Lawrence and Mayte Garcia ... and the other "Hollywood Exes" were clearly not in her league.

The trio attempted to sing "Hold On" by En Vogue as well (video below) ... but there's a lot less butt shaking.

Our apologies.

Paula Patton can still put on a happy face -- just days after announcing her separation from husband Robin Thicke, Paula arrived in L.A. with a big smile ... and no wedding ring.

The couple announced they were splitting this week -- and as we reported, the marriage meltdown stemmed from Robin's scandalous behavior with other women ... Miley Cyrus in particular.

Robin has pulled out all the stops to save his marriage -- canceling several tour dates -- but Paula's not budging.

Simon Cowell is not a slave to convention ... because his baby did what most don't -- and what some doctors say is dangerous for newborns ... his kid jetted to Miami for some fun in the sun.

As for flying ... there's a risk for mere mortals because of germs --- newborns are fragile because of their developing immune system ... but Simon flies private so it clearly minimizes the risk.

But some docs do advise against any flying because of pressure during the ascent and descent.
