Michael B. Jordan and Lori Harvey made their unlikely relationship official on Instagram over the weekend.

The "Black Panther" star shared a series of professional photographs with Lori on the social media app over the weekend. Michael, 33, captioned the post with a black love heart and exclamation marks, seemingly confirming he is heterosexual.

Lori, 23, also took to her own IG profile to post a series of polaroids from the same shoot of the pair looking loved-up in front of a Christmas tree.

Romance rumors were swirling around the couple during the Thanksgiving break, when they were seen together in Lori's native Atlanta.

The day before New Year's Eve, they were spotted stepping off a private jet together in Salt Lake City, Utah, where they reportedly rang in 2021 together in the wintery ski resort.

Lori - who was adopted by radio and TV host Steve Harvey after he married her model mother Marjorie - has previously been romantically linked to entertainment mogul Sean Combs, his son Justin Combs, rapper Future and singer Trey Songz. She was also engaged to Dutch footballer Memphis Depay in 2017.

After being named their Sexiest Man Alive last year, Michael told People magazine of the attributes he was looking for in a girlfriend.

"A sense of humor, true understanding - because (an actor's) life is not conducive to a relationship, it’s really not," he told the publication.

The actor continued, "Somebody that's nurturing .... That's probably why my a*s is still single, but yeah, it's a list."

The "Just Mercy" actor has previously been linked to Swedish singer Snoh Aalegra, model Cindy Bruna and actress Kiki Layne.
