PICTURE EXCLUSIVE: Supergirl's Melissa Benoist can't keep her hands off co-star Chris Wood as duo confirm romance in Mexico

Melissa Benoist and her Supergirl co-star Chris Wood have taken their romance public.

The pair put on a very affectionate display as they enjoyed some beach time in Cancun, Mexico together this week.

The 28-year-old actress couldn't keep her hands off the Ohio-born hunk as they frolicked in the ocean together.

The actress, clad in a black high-waist bikini, kissed and embraced her beau by the water's edge.

Wood coordinated with some black swim-shorts which showed off his muscular frame.

Wading through the water together the pair intertwined their fingers. At one point Wood had his leading lady in a fit of giggles as she threw her head back and placed a hand on his arm.

The couple's vacation came just a week after dating rumors arose surrounding the pair.

They were recently spotted together at LAX airport in Los Angeles where Chris wheeled Melissa's luggage as well as his own. And, adding to speculation that the pair are now an item, just hours before they were snapped at the airport, Melissa was spotted walking Chris' beloved dog, Drift, alongside her own smaller pooch, Farley.

The stars have split from their former partners within the past three months and are both single.

In Supergirl, Melissa plays the titular heroine while Chris plays Mon El, who eventually forms a romantic relationship with her feisty character. Both stars' love lives have recently played out in the public eye.

In early January, it was reported that Chris had split from his girlfriend and former Containment co-star, Hanna Mangan-Lawrence, 26.

Meanwhile, Melissa filed for divorce from her husband of just under two years, Glee star Blake Jenner, 24, in late December.
