AceShowbiz - New dating alert? Following his messy divorce from Stephen Belafonte, Melanie Brown a.k.a. Mel B is allegedly moving on with a younger hunk. The Spice Girls member reportedly is hooking up with "High School Musical" star Zac Efron, thanks to a super-exclusive dating app in which they allegedly exhange flirty messages.

According to The Sun, the 43-year-old beauty and the 30-year-old star had "a night of passion" after "The Greatest Showman" star "ended up driving over to her pad" in Los Angeles. "They hit it off and spent a few enjoyable hours together," a source claims.

"It wasn't exactly a meeting of minds," the source continues saying, adding that despite enjoying each other's company their relationship won't turn serious. "Neither saw it as long-term, but there was chemistry there. Mel thought Zac had an amazing body."

Zac was previously rumored to be dating his "Baywatch" co-star Alexandra Daddario. The two stars first sparked romance rumors after they were spotted walking their dogs together while they worked together for the 2017 movie. Alexandra, however, shut down the rumor. "We're very good friends," she said to PEOPLE. "Zac and I've worked together, and we're very good friends."

Meanwhile, Mel splitted from Stephen last year after being together for nearly 10 years. The judge of "America's Got Talent" cited "irreconcilable differences" as the reason for the divorce. The former couple is currently in custody battle of their 7-year-old daughter Madison.

Her ex-nanny Rusty Updegraff, however, gave his testimony that didn't seem to work on her favor. He dubbed Mel as unfit mother, claiming that she she was neglecting her children due to a drink, drugs and sex addiction to help the Spice Girl.
