Of course, Chappell also appeals to any human whose kink is cosmic.

Wendy Williams is glowing in a new pic with her son Kevin and dad Thomas, celebrating his big birthday -- and it’s no surprise, since that’s what scored her a judge’s blessing to hit up Miami.

Kevin kicked off his grandpa's birthday vibes by sharing the first IG pic of his mom's reunion with her dad for his big 9-4 Monday -- and Wendy was clearly soaking in every second of her freedom during her break from the assisted living facility.

Wendy was serving up major glam with her new glossy blonde 'do, holding her dad's birthday card with the caption on Kevin's post reading, "Happy I could make this happen for you Papa.. I said by any means and I kept my word."

Marcus Jordan is hoping to start on his dad's good side on his 62nd birthday ... wishing his pops a Happy Birthday weeks after dropping his name during the traffic stop that led to his DUI arrest.

The 34-year-old shared the shoutout on his Instagram Monday afternoon ... writing a simple "Happy Bday Dad" alongside some photos of His Airness' playing days.

Just three weeks ago, Marcus had a run-in with cops down in Florida after getting his car stuck on some train tracks. As they patted him down ... Marcus broke out the famous dad card -- telling cops he was the son of the six-time NBA champion.

Floyd Mayweather's just days away from his birthday ... and while he hasn't yet completed his 48th trip around the sun, the 50-0 boxing legend's kicking off the celebration a bit early!

TMZ Sports has learned Mayweather, along with ~400 of his closest family and friends, traveled to South Beach for a week of fun ... all to celebrate TBE's 48th birthday, officially on Monday.

Of course, Chris Rock's big break came on "Saturday Night Live" ... and, a lot of other show alum also attended his party -- including Kim K's ex Pete Davidson.

If Stevie Wonder doesn't sing at your birthday party, did you even have a birthday??? That's what some folks in an L.A. hot spot might be thinking after an impromptu performance.

This video's about as cool as it gets ... the legend was having dinner Thursday night with his son and some other family members at Teleferic in Brentwood, when he busted out his version of "Happy Birthday" -- y'know, the cool one.

We're told everyone in the joint stopped what they were doing to watch and listen to Stevie. You'll notice very few people sang along with him ... it's not like anyone was gonna do it better.

Danielle Haim hitting the big 3-5, and you bet her A-list crew -- plus her equally famous sisters -- showed up to celebrate in style.

Others braved the cold in style, including Ice Spice, who turned up the heat in a sleek, stomach-baring black ensemble.

Danielle’s got friends in high places -- Hollywood stars Shailene Woodley, Zoë Kravitz, Ayo Edebiri, and more also showed up to celebrate in style.

Vince Neil's birthday party in Florida may have been a lifesaver ... because it's the reason the Mötley Crüe frontman wasn't onboard a doomed private jet flight that killed his longtime pilot.

Vince's close friend, Lance Graves, tells TMZ … before Vince's private jet was involved in a fatal crash Monday in Arizona, Neil and his friends were in Florida celebrating his 64th birthday.

The rocker's girlfriend, Rain, was on the flight with her friend when it landed at Scottsdale Airport, lost control and crashed into a parked jet -- killing Vince's pilot -- but Vince was not.

Kelly Rowland is ringing in her birthday -- and she’s turning up the heat with some sizzling, balloon-themed IG pics that prove she’s the real gift!

There's gonna be a bunch of kissy faces and red hearts sent to Rosé's phone this week -- she's celebrating her 28th birthday!!!

The BLACKPINK singer has a ton to be thankful for on her special day -- she exploded as a solo artist after releasing her debut album late last year ... with her Bruno Mars collab "APT." surpassing PSY's "Gangnam Style" as the fastest K-Pop song to reach a billion views on YouTube.

While Ronaldo’s fine-tuning those abs on the pitch and in the gym, he’s also making sure his glow stays as golden as those trophies he's got.

Swimsuit season isn't actually a time of year, but a state of mind ... just ask birthday girl and Internet personality Hannah Stocking.

The comedienne turned 33 on Tuesday, but she has routinely proven that she is only getting hotter with age. Just take a peek at her most sizzlin' hot shots, many of which feature skin-showing 2-pieces that are nothing to laugh at.

Hannah appeared to channel Dominatrix Barbie in one pleather-looking bikini ... which barely covered up her curves thanks to some strategically placed buckles and cutouts. We're guessing vanilla isn't her favorite flavor!!!

Julia Fox has no problem talking about taboos on her "Forbidden Fruits" podcast ... and, she herself is a treat to look at -- and, we've got a collection of her hottest shots to celebrate her 35th birthday.
