Rachel Uchitel, who was launched into the spotlight in late 2009 thanks to her affair with golfer Tiger Woods, has some happy news to share: she's pregnant and can't wait to show off her baby bump. 
 
 "Expecting big things for 2012... Five down, Four months to go," she tweeted Tuesday along with a photo of her new husband, Matt Hahn, rubbing her growing stomach. "@MattyHahn checking out my baby bump at 5 months." 
 
 According to TMZ, Uchitel, 36, and Hahn, 26, were married in Nevada in October after dating for several months. 
 
 Aside from her affair with Woods, Uchitel was also in the news in 2010 when "Bones" actor David Boreanaz admitted to having an affair with Uchitel while his wife was pregnant. 
 
 After the affairs were made public, the former nightclub manager and hostess tried to use her newfound infamy to boost her career. Uchitel has appeared on the reality show "Celebrity Rehab With Dr. Drew" and, most recently, "Famous Food."

 Tiger Woods’ former mistress gave birth to Wyatt Lilly in May 2012 and the source said she thinks he’s going to try and wrest custody away from her. 
 
 “The lawyer obviously told Matt to beef this up to get sympathy and hope a judge would give him custody I’m assuming.” 
 
 As for Matt’s claims about a physical altercation the source said they’ve had “verbal mudslinging.”

 The cops were called to their NYC apartment the day after their daughter’s birthday because the source said Rachel needed someone to diffuse the very toxic situation and verbal abuse at the time. 
 
 “She has said that he shoved her when she had Wyatt in her arms. She did slap him after he called her names but that’s hardly cruel or inhumane. Rachel doesn’t beat people up. It’s absurd.”
