Amy Robach 'tries to keep her face straight' after reactivating her Instagram

Amy Robach has taken a little step back into the limelight as she and T.J. Holmes enjoy their first holiday together as a public couple.

A month to the day after their off-camera affair became well-known, pictures of the GMA3: What You Need to Know co-anchors kissing surfaced on Friday. In the pictures, the couple is seen holding hands as they stroll down a Miami beach while admiring the sights along the boardwalk.

A source told People magazine on Thursday that Robach, 49, and Holmes, 45, "spent the holidays together and are spending all of their time together right now. They are fully in a relationship. They are not hiding anything because they have no reason to."

The beach outing took place on Wednesday, the day before it was announced that Holmes was divorcing Marilee Fiebig, his wife of 12 years.

The source also mentioned on Thursday that Holmes had "told some people he was unhappy in his marriage and had been for a while" before filing for divorce.

Additionally this week, Robach, who is still wed to actor Andrew Shue, reactivated her Instagram account after Holmes did the same in late November when their workplace affair became public knowledge.

Robach has not yet shared any brand-new Instagram Stories or posts. Six days before the GMA3 romance was revealed, on November 24, she posted her last update, which depicts the journalist having a good time seeing Prague, the capital of the Czech Republic.

"Me trying to keep a straight face…," she wrote, adding, "Happy Thanksgiving"
