Hayden Panettiere performed a striptease earlier this month for boyfriend Milo Ventimiglia’s 31st birthday, ripping off a Velcro-lined version of her cheerleader outfit to prance around in red lingerie. Also on hand to enjoy the show? Everyone who happened to be on the Heroes set that day. Happy birthday, Milo! A source told Digital Spy

“Hayden asked the wardrobe girls to make her a Velcro-lined version of the outfit she wears on the show. As she sang ‘Happy Birthday’ to Milo in front of cast and crew during lunch she ripped off the costume to show off her sexy red lingerie [sic] in a bump-and-grind striptease. Milo’s face went bright red.”

If there’s one thing boys like for their birthdays, it’s their girlfriends showing tits and ass to the people he works with. Believe me, they eat that shit up. Even better if you start grabbing singles with your ass cheeks and smashing the guys from accounting’s faces between your boobies. Now, for a special occasion like an anniversary or Christmas, you should skip the T & A show altogether and get right to blowing his boss. Make sure you’ve wrapped his boss’ balls in tissue paper and tied one of those curly ribbons around it so that when he’s teabagging you in the break room, your boyfriend can see his special gift on full display. Remember, any good gift is one part thought, two parts penetration presentation!
