Jenny McCarthy 2012: Parties in Las Vegas Post-Brian Urlacher Breakup

After announcing her breakup from football star boyfriend Brian Urlacher on Thursday, model-comedian Jenny McCarthy hit the streets of Las Vegas over the weekend with her sister and gal pals in tow to celebrate her newly single status.

To get rid of her bad-luck-with-love vibes, McCarthy and crew hit the dance floor at Mirage's 1Oak Nightclub on Friday night. On Saturday the 1994 Playboy Playmate of the Year tweeted a picture of her and her sister JoJo with the caption:

@JennyMcCarthy: "Uh oh. Me and my sis @makeupjojo together again. Let the games begin sister."

The 39-year-old funny woman recently told people.com, "I am just working a lot. I moved to Chicago and my son is really happy. My next book - 'Bad Habits Confessions of a Recovering Catholic', is coming out in October and I am just getting ready for my television show."

McCarthy began dating Chicago Bears linebacker Brian Urlacher in April, and after a short-lived romance released a statement on Friday that, "Brian and I have decided to turn our romance into an amazing friendship. I will continue to be the biggest cheerleader for him."
