Joe Manganiello made his relationship with his new girlfriend Caitlin O'Connor red-carpet official Saturday, five months after filing for divorce from Sofía Vergara.

During the Children of Armenia Fund (COAF) Gala at Cipriani in New York City, Manganiello, 46, and the 33-year-old actress made their first red carpet appearance as a couple.

The "True Blood" actor was honored with the COAF Humanitarian Award at the event.

The "Magic Mike" actor sported a classic black suit and tie over a greyish-blue button-down, as seen in photos published by Page Six.

Meanwhile, the "Winning Time: The Rise of the Lakers Dynasty" star dazzled in a velvet emerald green dress with a plunging neckline, corset bodice, and a thigh-high side slit.

O'Connor accessorized her ensemble with matching emerald green drop earrings along with an understated bracelet.

The actress rocked a sultry makeup look, including bold eyeshadow and a rosy pink lip. Her hair was elegantly styled in a sleek ponytail.

The couple's joint appearance on the red carpet wasn't unexpected, considering rumors of their relationship surfaced just two months after Manganiello and Vergara announced their separation.

Romance rumors began circulating in September when Manganiello and O'Connor were spotted leaving a Gold's Gym in Venice, California, and driving off together, as reported by E! News.

Page Six reported in the same month that the "Kill Room" actor and the "Electric Love" actress were "casually" seeing each other.

The two met at an "unofficial" after-party for "Winning Time: The Rise of the Lakers Dynasty" while soaking in the hot tub, according to TMZ.

Meanwhile, reports indicated that Vergara, 51, has also moved on from her relationship with Manganiello.

Since late October, the "Modern Family" alum has been spotted enjoying several dates with orthopedic surgeon Justin Saliman.

Photos obtained by People last month showed the actress on a date with her rumored new boyfriend at the Italian restaurant Giorgio Baldi in Santa Monica, California.

Manganiello and Vergara announced their separation in July through a joint statement.

"We have made the difficult decision to divorce. As two people that love and care for one another very much, we politely ask for respect for our privacy at this time as we navigate this new phase of our lives," the exes said.

An unnamed source also told People at the time, "They have been growing apart for some time now and tried to resolve things, but they are focused on different areas of their lives."
