MICHAEL STRAHAN was dating his personal trainer – but now he’s seeing a YouTube beauty who broadcasts from bed!

Exclusive photos obtained by The National ENQUIRER show the 43-year-old former NFL star with brand-new squeeze Marianna Hewitt. The canoodling couple was caught at the Tao nightclub in Phoenix, Ariz., in town for the Super Bowl.

Marianna, 28, is a self-styled “product junkie, fashion addict, avid traveler and amateur photographer,” and was one of three Social Media Correspondents chosen to cover the 2015 SAG Awards.

The sexy video siren had lots of fanatical followers tuning in for her online reporting – which included shots of scantily clad Marianna chatting beneath bedsheets!

Meanwhile, Michael – star of “Live! with Kelly and Michael” and already worth an estimated $45 million – has doubled his hosting duties with a stint on “Good Morning America.”

The TV star called off his long engagement to Eddie Murphy’s ex-wife Nicole last year, and Nicole was reportedly also in Phoenix for the Super Bowl while getting close to NFL star Larry Fitzgerald.

Michael moved on to personal trainer Latreal Mitchell – and they both still live in the same swanky apartment building in New York City.

A close friend told The ENQUIRER: “There’s bound to be some difficult moments for Latreal when she next sees Michael after spying the photos of him with Marianna.

“It appeared Latreal had been pumping up his heart in addition to his abs – but now she clearly doesn’t have Michael all to herself.”
