Susan Kelechi Watson and Milo Ventimiglia were all smiles on the red carpet at today’s AFI Awards luncheon.

MILO VENTIMIGLIA & SUSAN KELECHI WATSON AT AFI AWARDS

The pair star in family drama This Is Us, which was honored at the AFI Awards. Ventimiglia sported a classic black suit with his signature mustache, while Watson wore a gorgeous lilac chifon dress. The low-cut dress with a mermaid bottom was paired nicely with silver and rose gold high heels.

The actors looked cozy together, though do not appear to be dating. Ventimiglia has recently spoken on relationships with co-workers, specifically advising against them. “Bad idea,” he said. “Don’t s–t where you eat.” Perhaps the actor was speaking from experience, as he’s dated Gilmore Girls co-star Alexis Bledel and Heroes co-star Hayden Panettiere.

On the show, Ventimiglia plays the husband of Mandy Moore‘s character. “Mandy is one of the kindest, most amazing performers and women I’ve met in my life,” he gushed. “She is exactly as I’d heard. She is amazing.”

Moore was also present at the AFI Awards.

Here some of us celebrating our show being named one of #afi’s top 10 TV shows of the year (in the most incredible company I might add)…. missing you @sterlingkb1, @justinhartley and #roncephasjones! #pinchmemoment #thisisus
