What Serena Williams did after her stunning US Open loss

Serena Williams didn’t let her stunning US Open loss prevent her from partying with her family and friends.

After losing in straight sets to 19-year-old Bianca Andreescu in the final on Saturday, Williams, husband Alexis Ohanian, sister Venus and 12 more of her nearest and dearest rented out the entire top floor of Mexican restaurant Vida Verde Sunday evening, we’re told.

Williams and her guests arrived at 9 p.m. and ordered the restaurant’s entire menu, a spy told Page Six. They paired their feast with the spot’s Forteleza margaritas and partied until 2 a.m.

“Serena was in good spirits,” our source shared.

The group ended their late night with dessert.

Williams’ close pal Meghan Markle, who flew to the Big Apple to watch the match, didn’t join the party.
