On Monday Mel Gibson (53) was spotted at his Costa Rican ranch with Oksana Pochepa (24), who Mel appears to be dating. A witness said of the pair:

"Mel was laughing and joking. He did not look at all worried or concerned. You would never have guessed he is going through what could be a very expensive divorce."

Mel and Oksana have been dating for over a year according to Oksana herself. Oksana, who is a Russian popstar and model, said:

“We are different people, but Mel is a grown man and knows precisely what he wants and me too, I know what I want.”

“I would not like to say more right now.”

Oksana claims to have visited Mell on the set of a movie in Boston last summer.

Other reports say Mel might be dating more than one blonde. Mel and his estranged wife Robyn have been separated for 3 years, right after he was arrested for DUI, according to divorce papers filed by Mel’s attorney.

Robyn Gibson (53), formerly Robyn Moore, has filed for divorce from Mel Gibson (53). The estranged couple have been married for 28 years. Through their publicist, Alan Nierob, they released this statement:

"Throughout our marriage and separation we have always strived to maintain the privacy and integrity of our family and will continue to do so."

Robyn’s attorney Laura Wasser filed the divorce paperwork this morning in Los Angeles County Superior Court. The paperwork lists the reason as "irreconcilable differences," and lists the date of separation as "to be determined," which means she might want to post the date later when more of Mel’s earnings hit the bank account. The estranged couple have been separated for more than 2.5 years, and they do not have a prenuptial agreement.

Robyn was a former dental hygenist when the couple met and married June 7, 1980 with no wealth of her own. The couple have seven children, Hannah (28), twins Edward and Christian (26), William (24), Louis (21), Milo (19), and Thomas (9).

Robyn has asked the coufrt for joint physical and legal custody of Thomas, who turns 10 years-old tomorrow, and both spousal support and attorney’s fees.

Gibson’s net worth has been estimated to be more than $900 million.

It’s sad to see couples who have been through so much together split.

Mel Gibson did a Colonel Sanders spoof video for Jimmy Kimmel, and now KFC has spoofed Mel Gibson.

We liked Mel’s spoof better.

Mel Gibson played KFC’s Colonel Sanders in The Colonel on Jimmy Kimmel Live.

So good to see Mel has a sense of humor.

FYI: Mel grew the facial hair just for this short movie.
