After his team won their 27th World Series — beating the Philadelphia Phillies 7-3 — New York Yankees slugger Alex Rodriguez and Kate Hudson hit NYC hot spot 10ak, along with Rodriguez’s mom, Lourdes Navarro, and his sister, Suzy.

They celebrated alongside Yankees shortstop Derek Jeter and his girlfriend Minka Kelly. Rodriguez, 34, and Hudson, 30, “got there at 2 a.m., but Kate left after a half-hour while A-Rod stayed close to 5 am.,” a source tells “Minka and Derek seemed really happy, as did they all, and didn’t leave until 5 as well.”

Since meeting Rodriguez this past May, Hudson has followed him closely during the winning season, attending games in Miami and Toronto.

At Yankee Stadium Wednesday night, she and dad Kurt Russell cheered on (along with Spike Lee, Donald Trump, Regis Philbin and Mary J. Blige, who sang the national anthem).

Although she denied engagement talk in the December issue of British Elle, Hudson is more than smitten with her beau, Us Weekly recently reported. Us also reported that Hudson has been mellowing out Rodriguez, a notorious egomaniac.
