Zac Efron and Alexandra Daddario sparked dating rumors in 2017 when the actors played love interests in Baywatch. The rumors heated up a couple weeks ago when Efron wished Daddario happy birthday on Instagram.
"Happy birthday to one of the the most real, down to [earth], stunning, intelligent, creative, loving, and most rare Pokémon ever created #alexdaddario," Efron captioned a photo of Daddario sitting on his lap.
The dating rumors burst into flames Thursday night (4/5) when fans caught Efron flirting with Daddario on Instagram-- this time in a comment on one of Daddario's photos.
"Two hot bitches," Efron commented, along with a string of emojis, on Daddario's photo with her dog.
