Is breaking up the new trend in Holly-weird? While not even divorced from wife Robyn Moore yet, Mel Gibson and baby #8′s mama Oksana Grigorieva have called it quits. The pair enjoyed a roughly one-year relationship, resulting in the birth of their daughter, Lucia, who is now 5 months old. Mel & Oksana made their relationship public in April 2009, the same month Mel filed for divorce from his wife, ending nearly 30 years of marriage that resulted in seven children of their own.

Per People:

“They just drifted apart,” says a close friend of the couple of the amicable split. “They’re both working hard on their careers and trying to raise a sweet baby together. They’re still friends and they’ll both raise Lucia together.”

It seems it’s also the end of the line for Melissa and Tammy Etheridge after nine years and two children together. They tied the knot in a legally non-binding ceremony in September 2003, exchanging vows barefoot under an arch of flowers at the Malibu home of Dick Clark. Tammy gave birth to the couple’s twins in 2006, joining Melissa’s two children from her previous relationship with Julie Cypher. In 2004, Melissa was diagnosed with breast cancer, and she has credited Tammy with helping her get through the battle. Rumblings of trouble began a couple months ago after Tammy posted some poetry on her blog that led to speculation that cracks were forming in the relationship.

Per People:

“Melissa and Tammy Etheridge are saddened to announce that they are now separated,” Melissa’s rep tells PEOPLE exclusively. The former couple add in a statement: “We ask for consideration and respect for our family as we go through this difficult period.”

CNN talk show host Larry King has filed for divorce from his wife Shawn Southwick after nearly 13 years of marriage. Larry is on his eighth marriage, so a divorce isn’t all that surprising for him. Just as Larry was filing his papers, Shawn was filing her own divorce documents, asking for primary physical custody of the couple’s two son, as well as spousal and child support. They married from a hospital bed in 1997 while he was recovering from surgery to clear a blocked blood vessel.

Per TMZ:

In the divorce papers, filed moments ago in L.A. County Superior Court, Larry blames the split on “irreconcilable differences.”

Rumor has it that Elin Nordegren is preparing to file for divorce from Tiger Woods. Elin reportedly met with a divorce lawyer over the weekend while Tiger was competing at the prestigious Masters tournament. She opted not to support her husbands return to the golf course and is said to be none to thrilled with his return.

Per Radar:

Elin has grown disgusted with Tiger because she believes he returned to golf too quickly and wasn’t sincere about building a new life with her. She participated in his sex rehab therapy and a few months ago the couple was making progress. But once Tiger announced his return to golf, Elin grew cold and became convinced that Tiger was not serious about making up for his serial cheating.

A source close to Elin has revealed that she was also violently angry in response to a recent Nike advertisement that featured Tiger with a voiceover from his late father, Earl Woods. While it is unclear as to whether or not the Nike ad proved to be the proverbial straw that broke the camel’s back or if she had been planning on divorcing from her husband all along, if she follows through with her intentions she is expected to strike it rich.

All this is transpiring as Jesse James and Sandra Bullock are having major marital trouble and ex-footballer Tiki Barber reportedly left his 8-months pregnant wife for a perky blonde intern/babysitter. Is marriage sacred anymore?
