Actor Zac Efron has reportedly split from his girlfriend Sami Miro.
The High School Musical star has sparked speculation he is single again after deleting all photos of Sami from his Instagram.com page, and 'unfollowing' her on social media - leading fans to believe the couple has parted ways, reports PerezHilton.com.
Zac and Sami have yet to comment on the rumours, but the actor was noticeably missing from the model's side as she partied during the first weekend of California's Coachella music festival earlier this month.
The pair began dating in September, 2014, and made its red carpet debut as a couple at the Los Angeles premiere of Zac's box office flop We Are Your Friends last summer. Their last public appearance together was at the MTV Movie Awards on April 9.
Meanwhile, Zac has been keeping busy filming the new Baywatch movie adaptation in Georgia, where he was recently photographed taking a tumble as he ran along the beach with his castmates.
In photos obtained by TMZ.com, the 28-year-old is featured sprinting topless in his red lifeguard shorts, alongside co-stars including Dwayne 'The Rock' Johnson and Alexandra Daddario.
It is not known if the tumble was scripted.
Original Baywatch stars David Hasselhoff and Pamela Anderson have also filmed cameos for the upcoming film, which also features Bollywood beauty Priyanka Chopra and models Charlotte McKinney and Kelly Rohrbach among the other castmembers.
The movie, directed by Seth Gordon, is set for release in May, 2017.
