Channing Tatum better step up ( ) his game because we all know Justin Bieber has a thing for older women .

Jenna Dewan Tatum stopped by "The Ellen Show" on Tuesday and revealed that when it comes down to it, she's a major Belieber at heart. After explaining her husband's Valentine's Day surprise -- so cute, it's annoying -- the "Supergirl" actress revealed that she had an embarrassing run-in with the man, the myth, the legend: Justin Bieber.

Yeah, you're right. Legend takes it too far.

"I had a girls night out the other night with all my best girlfriends. And we were at this restaurant just totally chilling ... Then someone gets on the piano and starts playing a song and were like, 'This is really good ... it sounds like Justin Bieber.' And then it was like, ding, ding, ding, ding it all dawned on us at once, we were like thats Justin Bieber. We all completely fangirled out," she told Ellen.

"We turned immediately 16," Dewan Tatum continued. "We sent him a drink to say thank you for serenading us. He comes over to our table ... He looks to me and hes like, 'I saw your 'Lip Sync Battle'' and Im like, 'You did? I saw yours!' And then he goes, 'Can we take a selfie' and I was like, 'Sure! Yes, lets take a selfie.' And he goes, 'I want to send it to Chan hes my man crush.'"
