They're doing their part and joining the popular trend at the same time!

During the final stop of their Monster tour, Rihanna and Eminem decided to jump on the charitable bandwagon and complete the ALS ice bucket challenge on stage in the rapper's hometown.

The two performers took turns dousing each other with freezing water after the 41-year-old rapper nominated Denaun Porter, Rick Rubin and concert cohort RiRi for their fans to see. Needless to say, their reactions, like many others, were priceless.

Check out the video to see it all unfold!

He's back at it!

It's been months since Chris Brown brought down his graffiti monsters from his Hollywood Hills home but it appears he's gotten the itch once again and enlisted a friend to help him create his latest piece.

Breezy and his boy Alec Monopoly tagged a Norm's 76 gas station near Los Angeles' famed Sunset Strip on Friday with some interesting artwork, complete with Chris's signature monster and Alec's Monopoly man on full display.

"Me and @alecmonopoly getting down today @norms76service today!" Chris posted along with a photo of his masterpiece.

To add icing on the cake, the New Flame singer sped off blasting his own music once the piece was complete.

He knows how to flee a scene in style, huh?!

She's showing him where mommy works!

On Saturday, Gwen Stefani and her baby boy Apollo stayed close as they took a quick trip to a recording studio in Los Angeles. Getting him started super early!

The No Doubt singer, who's quite possibly the most stylish mom in Hollywood, loves to spend every moment with her children so bringing her youngest to work is nothing out of the ordinary.

As for her other job, Gwen's getting ready to join forces with fellow judges Pharrell Williams, Blake Shelton and Adam Levine in season 7 of NBC's The Voice, which is set to air Sept. 22.

Check out the trailer for the latest season below!

She's ballin'!

Yesterday, Kaley Cuoco showed off a bit of her workout style when she sported a Ballin' Paris baseball cap (styled after designer Balmain) while leaving yoga class with friends in Beverly Hills.

The 28-year-old Big Bang Theory star has been a fitness aficionado for quite some time, frequenting yoga classes all over Los Angeles, in addition to the work she puts in with her trainer.

"She really likes to work hard," Fitness Factory personal trainer George C. King, who sees Cuoco for hour-long strength training sessions twice a week, said. "Kaley is interested in her lower body, especially her butt, her legs and her abs. We do a lot of lunges, squat jumps and regular squats, plus leg curls and dead lifts."

We're sure hubby Ryan Sweeting appreciates that!

He's calling her out!

On Saturday, Justin Theroux decided to do his part in the fight against ALS as he completed the now popular ice bucket challenge and nominated fiancé Jennifer Aniston in the process!

The 43-year-old Leftovers star took on the challenge with relative ease thanks to the help of friend Jimmy Kimmel, who also posted the video online.

"I would like to challenge members of the Lab[yrinth] Theater Company in New York," Theroux said. "...David Lynch and because she's not here to see me do this -- Miss Jennifer Aniston."

Check out his reaction afterwards in the video!

Early this morning, gunshots rang out at popular nightclub 1Oak in Hollywood which resulted in famed producer Suge Knight getting shot multiple times. He's currently out of surgery in ICU and is expected to recover.

The incident occurred around 1:30 a.m. Sunday which led to the 49-year-old Death Row Records co-founder was shot in the stomach, arm and other places of his body. Surprisingly he was able to walk out on his own power before being taken to the hospital in an ambulance.

Chris Brown, who hosted the party, along with other celebs like Tyson Beckford, Derek Hough, and Robert Ri'chard heard the shots loud and clear inside the club which led to chaos amongst the crowd.

"It's disappointing that we as a society can't have fun or enjoy ourselves without any altercations sometimes," Brown tweeted hours after. "Miss me with the bulls--t!!!"

Video coming soon...

Are they together again or is it just a fling?

Selena Gomez was super tight-lipped regarding her relationship with Justin Bieber after leaving a salon in Los Angeles on Friday in an attempt to not fuel any speculation but the evidence says otherwise...

As X17 reported, the 22-year-old singer/actress was seen leaving Bieber's Hollywood Hills home Friday morning in what looked to be the third time she's done so in less than a week.

No one can say for sure whether these two will go back to being a couple, remain a fling or none of the above but one thing's for sure: they just can't get enough of each other!

...or better yet, after showing her support to the up-and-comers!

Last night, Jennifer Lopez appeared to be in good spirits after leaving Hollywood hotspot Avalon after a night of checking out some performances and partying. She can still hang with the best of 'em!

The 45-year-old entertainer was on hand to catch rising stars Iggy Azalea and Rita Ora perform their hit Black Widow as part of a pre-MTV Video Music Awards concert sponsored by Time Warner Cable and Lifeboat. No doubt she also witnessed Iggy's unfortunate fall during her Fancy performance, but showed love for her younger counterparts afterwards.

"We dem girls...fun watching these two cuties perform tonight, @ritaora @thenewclassic @jlo #Booty #blackwidow," Lopez wrote in an Instagram post along with a photo of the three backstage.

Nice to see the old school give the newcomers some love!
