Is Zac Efron Dating Baywatch Costar Alexandra Daddario??

Is Zac Efron finally tied down again?

Rumors have begun to circulate that Zac and Baywatch love interest Alexandra Daddario are dating IRL!

After meeting on the set of what should be called BAEwatch with that attractive a cast, the two supposedly hit it off and have been secretly dating for months already.

Apparently they couldn’t keep it under the radar ENOUGH during the MTV Movie & TV Awards on Sunday, in which they sat together and presented Millie Bobby Brown with the Best Actor in a Show award.

They reportedly giggled and snapped pics with one another all night.

Ch-ch-check out some of their flirting before and during the big show on Instagram (below)!

First, Alexandra posted a pic of the seating arrangements:

If you scroll through the comments you can see Zac being awfully sweet, writing:

“@alexandradaddario Heck yeah- I’m officially excited for the MTV awards. Thanks seating gods!”

Awww!

But is this just Zac being his charming self, or is there something more going on?

The next pic seems to show more solid evidence…

OMG, how cute! Zac wrote on this one:

“Prom “

Is he calling her the prom queen? Or the two of them Prom royalty?? They would be one HELL of a handsome couple.

One thing is clear — he is all up in gurl’s IG.

So what do you think, Perezcious readers??

Are they dating? Just pals? Engaged? Engaged in cynical viral marketing for Baywatch, in theaters May 25?? Ha!
