Also on the late-night shows: Patrick Stewart rails against the producers of "Harry Potter" and Hugh Jackman races Jimmy Fallon.

Jennifer Lawrence says you know you've hit bottom when Miley Cyrus looks concerned for your well-being. After partying a bit too hard following the Oscars, the actress ended up throwing up at a fancy party while Cyrus looked on.

"I was in such bad condition and I look behind me and Miley Cyrus is there, and is like, 'Get it together,' " Lawrence said on Late Night Wednesday. But hey, she got to meet Brad Pitt that night, so it wasn't all bad: "He smelled like sandalwood."

It was X-Men: Days of Future Past night on the late shows, with Lawrence's co-stars Patrick Stewart and Hugh Jackman also making the rounds.

On Comedy Central, Stewart railed against the producers of the Harry Potter films for never offering him a role. 

"Wouldn't you think Ian McKellen and I were a shoo-in for Harry Potter? Not one phone call," Stewart joked to Stephen Colbert. "It hurts. It still hurts!"

On The Tonight Show, Wolverine himself challenged Jimmy Fallon to a cooler scooter race. What's that? And why did they do it, you ask? Just watch.
