Steven Tyler and actress Leven Rambin were spotted seriously making out at a post-Oscars party.

Allegedly, the 24-year-old "Hunger Games" star attacked him with her tongue.  She denies, of course.

A source said: "She ran to him as he was posing for photos and started making out with him. I saw their tongues together. They were super making out."

The 64-year-old Aermosmith frontman kept kissing the actress while he held a woman in a red dress with his other arm, as everyone stared from their dinner tables.

After the session, "American Idol" judge Randy Jackson sat down and gave Rambin some water. But that didn't stop Steven. He pulled up a chair and sat with her. Their friends told them both to take it easy.
