Selena Gomez & Vanessa Hudgens Instagram Kiss PHOTO: Sorry Justin Bieber & Zac Efron, (Ex) Girlfriends Tease Flirty 'Chelsea Lately' Love

Are Selena Gomez and Vanessa Hudgens trying to get ex-boyfriends Justin Bieber and Zac Efron jealous?

Well, this playful BFF "kiss" might do the trick!

The "Spring Breakers" beauties both appeared on the finale episode of Chelsea Handlers hit E! series "Chelsea Lately." Apparently, they had some flirty fun backstage before the show even started!

Hudgens also shared the adorable pic on Instagram. Despite some online haters (especially Jelena supporters), several fans loved it:

rue_on: "You two are the best, i love you SO."

stephanianazare: "Hahaha perfects."

alexia_gorgeous: "So cute!!!!!!"

liza2014293: "Beatiful baby love u."

Just days after Gomez's fake "smooch" with Hudgens, the Biebs shared this snapshot:

So looks like they're back together again... Perhaps Gomez's recent "sexy" behavior on social media snagged the "Believe" crooner for good?
