Tiffany Not Alone, Now

10/3/2007 11:47 AM PDT
Tiffany, remember her? -- she celebrated her birthday like any 36-year-old mother of one would last night. She went to former Hollywood hotspot Hyde.

TMZ caught the former pop star and recent "Celebrity Fit Club" contestant coming out of the club, where earlier in the evening, the DJ played her biggest hit, "I Think We're Alone Now."

Tiff left the club holding the hand of a hunky younger man ... as her cute hubby, George Benn, walked alongside them. Happy Birthday indeed!
