Katy Perry wasn't the only one at the grand opening of 1 OAK Las Vegas at The Mirage last night -- Paris and Nicky Hilton were also on hand for the evening's festivities, and the ladies looked gorgeous as they posed for pictures outside the brand new hotspot.

We're not sure if Paris and Katy became new BFFs over the course of the night, but after this sweet tweet, it's definitely a possibility! "@KatyPerry looking gorgeous across the room," P gushed. "Love her hair & dress! #Stunning!" Awww!

Earlier in the day Paris spent time shopping with Nicky, and she also went to the Chanel Numeros Prives exhibit at the Wynn. "So many fashionable & interesting art exhibitions," Paris tweeted. "@KarlLagerfeld rocks!"

Russell Brand was spotted out and about in Hollywood yesterday, and the British comedian was expressionless as he carried his lunch into an office building.

Various online reports claim that Russell is back on the dating scene, and Us Weekly claims that he's trash talking Katy to his new ladies! "He's spoken terribly about Katy to them," a source tells the mag. As if that wasn't bad enough, it looks like things are getting serious with one gal in particular! "[Russell] told her he wanted her to move in with him after the divorce is final," the source added. So much for true love!

Yesterday Jessica Alba and her daughter Honor were snapped at The Honest Company's headquarters in Santa Monica, and yes, the 30-year-old actress is really wearing a denim vest. While Jessica is arguably one of the most stunning women in Hollywood, we're not so hot on this outfit. Of course, Jess is so pretty she can get away with almost anything, but you know it's not a good sign when you're 3-year-old daughter is dressed better than you!

Yesterday Demi Moore's 911 call hit the internet, and friends of the 49-year-old actress told dispatchers that she had collapsed after smoking a mysterious substance.

An unidentified female caller revealed that it was "not marijuana," adding that it was "similar to incense." Demi had difficulty speaking, convulsions and a fever, and now doctors are speculating that she may have smoked synthetic cannabis, also known as "K2," "Spice" or "herbal incense."

Dr. John Sharp, MD, a faculty member of Harvard Medical School explained to Us Weekly that the drug is similar to marijuana but "not necessarily safer" and it doesn't show up in most drug screenings. Some medical studies have linked the use of synthetic cannabis to psychosis, heart attacks and convulsions, so Demi's reaction does seem consistent with someone using the drug.

And that (along with nitrous oxide) weren't the only substances Demi was allegedly using. Prior to her trip to the ER, Demi had been drinking excessive amounts of Red Bull energy drinks, and a source told Us that she drank 12 cans in one evening!

Brett Ratner is reportedly interested in making a movie that would show "the real" Michael Jackson, and he recently met with Frank Cascio, author of “My Friend Michael" and a longtime pal of the late King of Pop.

Cascio reportedly met Jackson in 1984 and became his assistant and eventually his manager, and his book documents the singer's highs and lows, including child molestation charges and prescription drug use. Ratner was also friends with Jackson, and a source close to the director tells NY Daily News that he has toyed around with the idea of making biopic on the singer for a while. At the time of Jackson's death, Ratner told the LA Times that he “was the most inspirational person in my life ... When you were with him, you really felt like God was within him.” Hmm...

In other news, the teaser for the special MJ tribute episode of Glee has hit the web, and it features Darren Criss covering Jackson's hit, "Wanna Be Startin' Something". Click thru to watch!

She's still rocking hair the color of Smurfette's skin, but it doesn't look like newly single Katy Perry is singing the blues!

Last night the pop star co-hosted the GiveLove charity event with J. Molinari Jewelry designers Markus Molinari and Jason Arasheben at the grand opening of 1 OAK Las Vegas at The Mirage, and she looked absolutely amazing on the red carpet. The "The One That Got Away" singer been laying low since the news broke in late December that she was splitting from husband Russell Brand, so it's good to see her back out and about.

Katy and Marcus presented a check for $50,000 to GiveLove's co-founders, Patricia Arquette and Rosetta Getty, and other guests at the bash included Paris and Nicky Hilton, Scott Disick, Chris Evans, David Arquette, Christina Milian and Shenae Grimes. Sounds like a blast!

Charlie Sheen shot a Direct TV commercial in Los Angeles yesterday, and the actor appeared to be in great spirits when he took a quick smoke break.
