Random BFF Alert: Meghan McCain and Tila Tequila

A pregnant Heidi Montag may be April Foolery at its finest, but this bizarre BFF pairing was actually spotted on March 28, so it must be legit. And odd.

Meghan McCain and Tila Tequila, the trashy bisexual reality TV star, shared an early lunch Saturday at the Chateau Marmont in West Hollywood.

"You could totally see the girls getting along," a source who observed the strange pairing said. "They seemed to be longtime friends."

During their hour-long lunch, the former nude MySpace mainstay and the daughter of U.S. Senator and former presidential hopeful John McCain were overheard chatting "about everything from politics to pop culture," adds the source.

How did these two possibly hook up?

Rumor has it Tila Tequila, 27, read somewhere that Meghan McCain, 24, looks up to her and burlesque dancer Dita Von Teese for some reason.

"They found each other on Twitter and got in touch shortly after," the source tells Us Weekly. "They definitely seemed to be fast friends."

Of course. No word on whether Meghan McCain's weight was an issue the two discussed at lunch, or whether they will become more than friends. Come on, it's Tila Tequila. We had to go there. You know you were thinking it.
