According to various online reports, Jay-Z spent more than $300,000 on the Sunday night release party for Watch the Throne, his collaboration with Kanye West!

The party, at Miami's Fontainebleau, started with dinner at the hotel's Italian restaurant, Scarpetta, where Jay-Z spent thousands.

The restaurant stayed open extra late for Jay and his entourage -- they dined on tomato basil and lobster mac and took shots of tequila.

The party continued at LIV nightclub, where the group downed more than 18 bottles of Ace of Spades and Jay spent $250,000 on Armand de Brignac champagne, plus a $50,000 tip!

Justin Bieber has thousands of screaming fans, but Cher isn't one of them.

While Cher looked like a total rockstar while attending a private swag bag party over the weekend in Brentwood, she acted more like a diva while meeting the "Baby" singer.

A source told the New York Daily News that Cher was chatting with Bridesmaids star Melissa McCarthy recently about her run-ins with Justin and Jaden Smith.

Turns out the first time Cher ran into Justin, she asked someone nearby "if he was in show business." Ouch! But in the same conversation, she happily told McCarthy that she took "a picture with Jada's son." Even funnier? The teens are BFFs.

Sorry, Justin - bragging rights go to Jaden!

Pink is definitely a creature of habit.

The new mom made a run to her local Malibu Starbucks in her fave post-pregnancy sweatpants Monday. Iced coffee and comfy sweats may be two of the "Raise Your Glass" singer's favorite things, but we love that she still spiced up her casual look a bit with a bright red graphic V-neck and black hat.

The only thing missing during the quick trip out was Pink's precious baby girl Willow, but even Mom needs a caffeine break sometimes!

On June 11th, Russell Armstrong was seen with his wife, Taylor, at her birthday party at Beso nightclub and restaurant in Hollywood.

X17 spoke with Russell at the time. He told us "things are good," and both he and Taylor denied reports that they were divorcing, calling the stories "completely false."

Russell even told us the secret to a good relationship. "Hard work and commitment," he said, smiling.

But in July, Taylor filed for divorce, alleging that Russell had been verbally and physically abusive to her. He did not deny the claims, saying he had pushed her and that being on Bravo's show had pushed the couple "to the limit."

The couple also reportedly had major financial problems. They were being sued for $1.5 million, and Russell, an investor, had filed for bankruptcy in 2005, claiming at the time that he had less than $50,000 in assets and was up to $10 million in debt.

Russell, 47, hanged himself Monday night at his apartment on Mulholland Drive and was pronounced dead by police.

Jessica Simpson seems to appreciate the vocal talents of fellow powerful divas!

The young mogul and her sexy fiance Eric Johnson were all smiles as they made their way into the Greek Theatre in Hollywood to catch Adele in concert.

Ms. Simpson, wearing funky maroon earrings and an all-black ensemble, showed off her sculpted and tanned legs. Not sure if those wedges are concert appropriate, but we're lovin' the look!

See who else rocked out with the "Rolling In The Deep" singer in the gallery below.
