Did Milo Ventimiglia have a little too much fun on the night of the 2018 Golden Globe Awards? The actor stopped by HBO's Golden Globes after-party at the Beverly Hilton in Beverly Hills, California where he accidentally slipped and fell into a pool after the annual gala held on Sunday night, January 7.

Words spread that someone fell into the pool after some fellow partygoers took to social media to report the incident. "At HBO's Golden Globes party. Believe I just saw Milo Ventimiglia from This Is Us slip and fall into the pool, which is mostly covered but open in one spot...," so NPR's Eric Deggans tweeted along with a picture of the scene.

The "This Is Us" actor then took to Instagram after the party to confirm the mishap. "Good time at the Globes tonight," he said on Instagram Stories while holding a script. "Back home studying for tomorrow...and yes, I fell in the pool." His hair looked wet.

He also sent a congratulatory message to his "This Is Us" co-star Sterling K. Brown who won Best Performance by an Actor in a Leading Role at the 75th annual Golden Globe Awards. "Congratulations Sterling, excited!" Milo said. "And everyone else, great night!" Sterling made Golden Globes history as the first black man to win an award in the category.

"This Is Us" was nominated for two other awards at the Sunday night ceremony, but lost it out to "The Handmaid's Tale" in Best TV series - Drama category. Meanwhile, Laura Dern of "Big Little Lies" beat Chrissy Metz and other nominees for the Best Performance by an Actress in a Supporting Role in a Series, Limited Series or Motion Picture Made for Television title.

Milo's hit family drama series "This Is Us" will return with new episodes starting Tuesday, January 9 at 9 P.M. on NBC.
