Popsugar Celebrity Alexandra Daddario Are Zac Efron and Alexandra Daddario Dating? Zac Efron and Alexandra Daddario "Aren't Officially Dating," but These Photos May Prove Otherwise 6 April 2018 by Monica Sisavat Solís First Published: 2 April 2018 Image Source: Getty / Cole Bennetts Zac Efron and Alexandra Daddario have been generating romance rumours ever since they starred together in Baywatch last year. The pair played love interests in the film and have been hanging out a lot recently. So, what is the truth? Are they or aren't they a couple? Well, according to People, Zac and Alexandra have been "seeing each other on and off" since 2017, but "they are not officially dating." Alexandra also shot down dating rumours when she attended the Billboard Music Awards back in May 2017. "We work together closely; he's my love interest in the film," she told E!'s Jason Kennedy. "I understand why people would go crazy over something like that, but Zac and I are very good friends." Even though the 32-year-old actress may have previously said that they aren't a couple, a whole lot has happened since then. Not only did Alexandra ring in her birthday last month with Zac by her side, but Zac recently called Alexandra "one of the most real, down to Earth, stunning, intelligent, creative, loving, and most rare Pokémon ever created" on Instagram.
