Rachel Uchitel, Tiger Wood’ ex-mistress, has announced that she and new husband Matt Hahn are expecting their first baby.

Rachel Uchitel showed off her new pregnancy with a photo posted to Twitpic.

“Expecting big things for 2012…Five down, four months to go,” Uchitel tweeted.

In 2009, Rachel Uchitel, 36, was the first woman to come forward as Tiger Woods’ mistress. It was purported that she had received $10 million from Tiger Woods as hush money, but had to later return a large amount of it after appearing on shows such as Celebrity Rehab . Rachel Uchitel went on the Dr. Drew show for a “love addiction.”

Rachel Uchitel and husband Matt Hahn we’re married in October in Las Vegas. An insider told Life & Style at the time that Uchitel was pregnant and the pair planned to have a bigger wedding after the baby arrives.

Rumor has it that a pregnant Rachel Uchitel already has a baby registry, which includes a Bugaboo stroller and indicates that the couple is expecting a baby girl.

Congrats to the couple!

Mel Gibson’s divorce to ex-wife and mother of his seven children, Robyn Denis Moore, was finalized on Friday, leaving the actor with quite a big hole in his pocket. Robyn will walk away with half of his $850 million fortune, a payoff that will make it one of the biggest in Hollywood history.

Mel Gibson, who was married for 30 years, will also be required to hand over half of every future movie residual he brings home to his ex because the couple did not have a prenuptial agreement. In California, if there is no prenuptial agreement, spouses are legally entitled to half of everything earned during the marriage. Mel Gibson’s rumoured $850 million fortune includes $600 million from his movie, The Passion of the Christ, alone. Other assets include $100 million in real estate investments and $75 million for film and tv projects Mel Gibson,55, produced.

Robyn, 55, who met Mel Gibson while she was a dental nurse in the 1970′s, defended the actor during a 2010 custody battle with his ex-girlfriend, Russian musician Oksana Grigorieva, who Gibson had a daughter with while he was separated. Grigorieva accused Gibson of domestic violence, to which Robyn filed a sworn affidavit saying “Mel was a wonderful and loving father” and never abused Robyn or their kids.

Ladies, Matthew McConaughey is officially off the market.

The hunky dad of two proposed to his longtime girlfriend and mother of his children, Camila Alves, over the Christmas holiday.

“Just asked camila to marry me,” Matthew McConaughey posted on his WhoSay account, along with a photo of the engaged couple.

Camila Alves and Matthew McConaughey, who are the proud parents to son Levi, 3, and Vida, 2, have been together for over 4 years. Matthew McConaughey has said that it took the “right woman” to want to settle down and have children. “[Alves] is the love of my life. Everything is right,” he said.

No word on where and when the couple will get married, but we’re guessing it will involve a beach and some bongos.

Congrats to the happy couple!!
