Gosh, people can be so fickle these days. Mark Wahlberg used to have a picture of himself and teen heartthrob Justin Bieber. But he revealed on 'The Tonight Show' (weeknights, 11:35PM ET on NBC) that the photo has been torn down. No way! Say it ain't so, Mr. Wahlberg! So, what was the problem with Justin Bieber?

Well, as Mark revealed to Jay Leno, the photo actually belonged to his 7-year-old daughter Ella Rae. Like so many other young girls, she was infatuated with Justin Bieber -- which led to Wahlberg appearing in a picture with the singer.

Then, Ella Rae heard that Justin had kissed "some girl -- Selena Gomez, or something." According to her dad, Ella was "all upset" and ripped the photograph down. Aw. Well, first crushes can be difficult. Now, Mark says, Ella likes Mitchel Musso, "or some other guy that I'm gonna have to strangle." (Wahlberg was vague on the details.)

Ella's love for "J. Bieb" led to rumors that Wahlberg would restart his, um, singing career by releasing a song with Justin. Sadly, this was not true. It was just a joke that Mark made for his daughter's benefit.

But even though they're not doing a song together, at least Wahlberg wasn't the one who tore Justin's photo off the wall. After all, Mark Wahlberg is generally a really nice guy -- he has a kind word for everyone (even animals). So we're happy that he's not feuding with Justin Bieber -- and we're glad that the pair are experiencing some "good vibrations" in their relationship. (Sorry; we couldn't resist.)
