These are the Rihanna photos you’ve been waiting for your whole life — down on all fours and bottomless. BOOM GOES THE INTERNET!!!

RiRi was posing for pics in the Hollywood Hills this week as part of a photo shoot for a French magazine … wearing some kind of bikini top and nothing else. To make it even hotter, there was even a guy whose job it was to pour water down her back.

She's hitting the road for her ARTPOP Ball tour next month and Lady Gaga clearly can't wait to bust a move.

The 28-year-old singer made a surprise appearance at BMP Nightclub in New York on Saturday for the Official Lady Gaga At Roseland after-party and showed off her pert posterior in a daring leotard. 

Gaga danced around the stage, showing off her moves in the revealing leotard, fishnet tights and her signature towering heels, and while she may have been wearing an attention grabbing blonde wig, the focus was no doubt on her revealing ensemble.

The star showed no signs of fatigue after performing at the Roseland earlier in the evening and put on an energetic performance at the after-show.

Gaga took to the stage alone as she strutted her stuff.

Her tattoo on her left thigh was clearly visible as through her fishnet stockings and she appeared to be in a world of her own as she showed off her moves. 

Never body-conscious, the star twisted and turned to show off her body from every angle.

The ArtPop hitmaker is currently completing a seven-night residency at Roseland Ballroom, which will end on April 7, with the closing of the legendary New York venue.

The 52nd Street theatre is closing its doors after 56 years, and the G.U.Y. singer is the final performer to take the stage.

'It's basically the only room in the city I haven’t played,' Gaga told The New Yorker recently, noting that Manhattan clubs are 'where I learned to be bold.'

The Roseland Ballroom will eventually be transformed into a 59-storey residential tower.

Gaga will then have almost a month off before she kicks off her ARTPOP Ball Tour May 4 at Florida's BB&T Center in Ft. Lauderdale.

Entourage was a marginally good show that got marginally worse and worse as the series went along. Even tits couldn’t save a tired storyline and emotionally overwrought little tiny men, and tits can save almost anything. Somehow Marky Mark and show producers convinced the media  world that there was a groundswell of support for a feature film, if only all the out of work actors from the show would agree to do the movie. Just like they convinced everybody it was a hit show for so many years, even though it had a fraction of the audience of more popular cable shows. It was a show about Hollywood that was very popular in Hollywood. Eight times more people watch Game of Thrones on the same channel. Now, after a year of fake hype about whether or not a movie would get made, the movie is getting made. Bikini model Nina Agdal was on set the first day picking at her bikini bottom. You could see that as a decent omen. Or maybe just a chick with an itchy ass.

Rihanna performs at the New Orleans Arena on Friday, November 15, 2013. It was the final performance of 100 shows for the Diamonds World Tour. 

Here are some behind the scenes pics of Monica Bellucci in a wet and see through dress on the set of The Milky Way. There’s no school like the old school, or in this case, the veteran school of hotness, with classes taught by long time Italian film actress and model, Monica Bellucci. On the set of her new film Monica isn’t quite topless, but all but thanks to a sheer top and some blessedly placed water. I can see happiness. Enjoy the view!

If you haven't had enough of those Victoria's Secret girls, and Heidi Klum in particular, here's one last little look at Heidi, and her ass crack too. Yes, that's right, not only so we get Heidi Klum cleavage from the front, now we get cleavage from the back. Even hotter than all that, though, is the fact that you can clearly see that Heidi is going "commando." Add to that the super short skirt, and you've got a Britney Spears moment just waiting to happen. Sadly, Heidi's too smart for that.

Ke$ha goes all out with glitter at the2013 iHeartRadio Music Festival on Saturday evening (September 21) at the MGM Grand Garden Arena in Las Vegas, Nev. The 26-year-old entertainer performed her hit “Die Young” before she was joined on stage by Joan Jett to sing the classic “Bad Reputation.” Earlier in the month, Ke$ha hit the carpet while arriving for her performance at 1 OAK Nightclub at The Mirage Hotel & Casino.
