Justin Bieber and Ariana Grande Kiss, Flirt on Twitter, 'Yours Truly' Songstress Tweets Fans 'Chill Out!' [PHOTOS]: Selena Gomez Jealous, Moves On with David Henrie?

Ariana Grande and Cody Simpson tagged along with Justin Bieber on his "Believe" tour pit-stop in Tampa, Florida on August 8. Following the concert, the 20-year-old Nickelodeon starlet and 19-year-old "Baby" crooner got a little cozy backstage! Grande posted a photo on Twitter of the Biebs' passionately kissing her cheek, and Beliebers quickly went completely crazy! After some back-and-forth Twitter "flirting," Grande eventually told fans they all need to "chill out." Nothing's going on romantically... she's currently dating Jai Brooks of the Australian band Janoskians. Still, is Selena Gomez jealous of Bieber's flirtatious ways... or has she also moved on, with Disney actor David Henrie?! Read on for more juicy deets...

So, here's how the "flirting" first started out on Twitter... involving Grande's Nonna:

@ArianaGrande: "My grandmother is now in love with @justinbieber."

@justinbieber: "@ArianaGrande tell grandma I said whatup. Lol. Welcome to the tour."

@justinbieber: "@ArianaGrande by the way the new song with @BigSean I like it."

@ArianaGrande: "Nonna met her love!!! Nonna, Grandpa and @justinbieber :)."

@justinbieber: "@ArianaGrande post that pic and tell your grandma she is a cutie."

@ArianaGrande: "@justinbieber you're crazy and nonna says thank you, she loves you."

Well, following all of the Belieber backlash, Grande tweeted:

@ArianaGrande: "Everyone, girls are allowed to be friends with guys. I'm a lady. Chill out."

And as a joke:

@ArianaGrande: "Oooooo scandalous!!!!!! Lol."

Grande's currently in a serious relationship with Jai Brooks... she's been friends with Bieber for a long time. And that's as far as things go.

But is the Biebs chasing after another Selena Gomez look-alike? Grande claims she has very little in common with the "Spring Breakers" beauty. During an interview with OMG! back in April she said:

"I don't really see [the comparison]. We both started out in children's television, I think we share that in common and we are both doing music.. But we are really nothing alike, if you look at us and compare our sounds we aren't that much alike. She has been incredibly successful thus far in her career and I will feel lucky if I am just as successful."

As for Gomez, she's not wallowing in Jelena heartbreak:

selenagomez: "Homesick..."

This is a pic of Gomez cuddling up with former "Wizards of Waverly Place" co-star, David Henrie. Hmm... would they make a cute couple?

FYI: Grande's debut album "Yours Truly" hits stores on Sept. 3.
