Katy Perry was one of the many guests who attended Elton John’s 20th Annual Academy Awards Viewing Party over the weekend, where she reportedly called her ex, Russell Brand, “lame.”

The British comedian has been spotted with two different women since his split from the ‘Teenage Dream’ singer, most recently with Mexican artist Oriela Medellin Amieiro in L.A. However, the news didn’t seem to affect Perry on Sunday night.

According to Hollywood Life, the 27-year-old pop star had a great time at the Oscars event, which benefits the Elton John AIDS Foundation. Us Weekly reports that the newly single singer got a little “tipsy” at the bash, and even bid $50,000 on a cooking lesson, half of a $100,000 winning bid, which she she split with movie producer Steve Tisch.

“Katy was totally in her element and around people that really care about her,” a source tells Hollywood Life. “She didn’t seem upset once, in fact she was laughing and acting like her old self.”

The insider continued, “Katy thinks Russell is so lame. She’s knows there’s something better out there.”

Perry wasn’t the only A-lister at the soiree — Miley Cyrus, Adam Lambert, Ashley Tisdale, Vanessa Hudgens and many more attended the star-studded event.
