Spotted: Diddy And Rick Ross Rock The Pink Elephant

Every day a multitude of stars wanders through the halls of MTV News to talk about their latest projects and goof around with our intrepid correspondents. But sometimes we catch stars elsewhere, and that's why we put together Spotted!, a daily compendium of stars in the wild.

Rick Ross' Deeper Than Rap was one of the best, most overlooked albums of 2009. Diddy's Last Train to Paris promises to be one of the finest records of 2010, so perhaps it's only right that the two hip-hop titans have spent a lot of quality time partying in the past few months. They helped open up a new club in Las Vegas just after the calendar turned, and the pair spent Monday night (January 18) at Pink Elephant in New York. It was a well-deserved party for Ross, who spent most of Monday organizing a blood drive for the benefit of victims of the earthquake in Haiti. Ross, a native of Miami, told AllHipHop, "We have to come together to assist Haiti in anyway possible. Give blood, donate what you can and remember the relief efforts for Haiti need to be long term." He joins hip-hop stars like Wyclef Jean, Jay-Z and David Banner in the effort to aid the devastated Caribbean island that was torn apart by a major earthquake a week ago.

Plenty of other stars made it out over the long weekend, as Adam Sandler jawed with Jack Nicholson at the Lakers game in Los Angeles and Taylor Momsen was spotted on the set of "Gossip Girl" in New York. Click here for these photos as well as the entire "Spotted!" archive, which features over 300 candid shots of stars like Britney Spears, Beyoncé, Madonna, Justin Timberlake, Adam Lambert, Justin Bieber, Taylor Swift, Rihanna, Shakira, Jay-Z, Susan Boyle, Mariah Carey and Timbaland!
