After smooching Jessica Alba's husband Cash Warren, it seems as if Lindsay Lohan has moved on to a new guy.

On Friday, the actress, 23, partied all night with How I Met Your Mother star Jason Segel in West Hollywood.

She was then photographed leaving his home the next morning.

Under her arm: Segel's Dracula puppet from his 2008 comedy Forgetting Sarah Marshall. caught up with Segel, 29, Sunday at the Cracked Xmas 12 Gala event in Los Angeles.

But when asked about Lohan, he laughed.

"Oh, man, no..." he said as he walked away.

A rep for the actor tells "Jason had a party, and he let several people stay over as the party ended late. There's absolutely no romantic relationship going on with Lindsay Lohan and Jason Segel, period."
