Adam Lambert With Miley Cyrus, Darren Criss, Katy Perry & More At The Elton John Oscar Party [PHOTOS]

Adam Lambert was the man of the night at the 20th Annual Elton John AIDS Foundation Academy Awards Viewing Party at The City of West Hollywood Park last night (February 26) in Beverly Hills, California.

The singer attended the event with his boyfriend Sauli Koskinen got to hang out with friends Kelly Osbourne and Katy Perry, and it looks like he made a bevy of new ones as well.

Adam posed with everyone from Miley Cyrus to Darren Criss to Steven Tyler to Neil Patrick Harris. For the look on his face in the majority of the photos, Adam seemed to be enjoying himself immensely.

The event, which 900 people attended, saw some of Hollywood’s biggest names, but the focus wasn’t on the awards actresses won or the gowns they wore. John’s party served to raise funds for HIV/AIDS prevention and treatment and efforts to fighting the stigma associated with the disease.
