Rachel Uchitel has officially proven she is pregnant with her husband Matt Hahn by tweeting her five-month baby bump.

The 36-year-old nightclub manager has been rumored to be pregnant for months, but it is only now that she has officially revealed how far into her pregnancy she is and the baby's paternity details.

Expecting big things for 2012...Five down, four months to go, she tweeted along with a picture of her baby bump.

Lucky for Tiger Woods he has not been connected with the pregnancy, but now that her husband Matt Hahn has been proven the father, he might have to watch out, as Uchitel seems to have expensive taste.

Uchitel has complied her baby register for her friends and family, which includes a $1000 stroller and $300 nipple pumps, the Daily Mail reported.

Other items on Uchitel's wish list include a $429 Johher stroller, $299 car seat and a variety of items including clothing, nappies, night-lights and humidifiers, according to the Daily Mail.

Uchitel married 26-year-old businessman Hahn in October at the Little White Chapel in Las Vegas. She told the world she married out of love and was serious about the relationship.

Matt and I were married in front of 12 friends at the Little White Wedding Chapel in Las Vegas, where everyone from Michael Jordan to Demi Moore and Bruce Willis, to Britney Spears were married, Uchitel told Radar online.

She talked about her so-called love addiction on Celebrity Rehab with Dr. Drew.

I don't have a trigger that makes me get into a relationship, Uchitel said on the show. I've never dated anybody. I don't do that. I don't know how to do that. I go right into a relationship. Usually the relationships I get into are intense. We're not talking about sex, we're just talking about the connection, she said.

On the show she was told that her past relationship issues were linked to abandonment. Her father and finance has both died and she grew up with witnessing her father's cocaine addiction, which caused traumas at a young age.

It was through her relationships that Uchitel became famous. She had multiple affairs with golfer Tiger Woods and actor David Boreanaz. She was also engaged to investment banker James Andrew O'Grady, who died in the Sept.11 terrorist attacks on the World Trade Center in 2001.
