ELIJAH & NICK
In a shocking revelation, Elijah Wood told Tonight Show host Jimmy Fallon that he's friends with Bachelor Nick Viall. "I've known Nick before he became the Bachelor, which is the craziest thing," Wood revealed. The Lord of the Rings star also confirmed that Viall is indeed on the show to find love, not fame. "It's real, yes [he's looking for love], he is," he told Fallon. "Here's the thing about Nick, I think a lot of people question whether he is real or if it’s really real him on the show, in the way that he's presenting himself, and that is him."

ANNA & JENNA
This friendship is so perfect we couldn't have dreamed it up if we tried. Anna Faris had Jenna Dewan Tatum over to record her podcast, "Unqualified" … and the two ladies broke it down, as Dewan Tatum showed Faris how to booty pop and writhe against a table. (As a good friend does.)

ANNA & ADAM
Kendrick and Lambert actually became friends as teenagers, before hitting it big. In a 2010 interview with Ryan Seacrest, Kendrick recalled seeing her pal at a party the year before. "He told me, 'You can't tell anybody but I tried out for American Idol and I got through Hollywood Week,'" she said. "I was like, 'Okay! You can't tell anybody but I just booked this movie [Up in the Air] with George Clooney!'" A year after that, they met up and "were like, you know, it's been quite a year for both of us," the actress said.
