On top of the world after winning the World Series, Yankees stars Alex Rodriguez and Derek Jeter celebrated with a night out in New York City with their teammates – and their Hollywood girlfriends Kate Hudson and Minka Kelly.

Following their triumph Wednesday, the group headed to 1OAK to toast their victory over the Philadelphia Phillies. And they made it a family affair: Hudson and A-Rod arrived at the club around 2:45 a.m. with his mother, sister, and Hudson’s step-dad, Kurt Russell, all in tow.

“Kate and A-Rod were affectionate with each other – hugging one another,” says a partygoer.

While Hudson skipped out after just over an hour, her stepdad and boyfriend stayed and bonding over the win. “They got along great,” says the eyewitness. “A-Rod hung out with Kurt most of the night. ”

They even sang together! “A-Rod stood on a banquette and sang to the song ‘We Are The Champions’ with Kurt as well as other party-goers,” adds the onlooker.

The bash was stocked with 200 bottles of Ace of Spades champagne, and other guests included Chace Crawford, Wilmer Valderrama and former Sopranos star Robert Iler.
