JENNIFER LOPEZ - MARC "NOT GOOD" FOR ME: JENNIFER LOPEZ is opening up about her split from MARC ANTHONY in the pages of the latest Vanity Fair. And although she doesn't share any details on why she walked away from the marriage, she did wax philosophical on the "hardest decision [she's] ever had to face."

"Sometimes we don't realize that we are compromising ourselves," she says in the interview. "To understand that a person is not good for you, or that that person is not treating you in the right way, or that he is not doing the right thing for himself -- if I stay, then I am not doing the right thing for me. I love myself enough to walk away from that now."

J. Lo adds that things went south when she returned to the spotlight. "We had the first three years of our marriage just for us. I wasn't working, it was mainly about him. Then we got pregnant. Then it became about the kids. And then I started working again." That, she reveals, led to her and Marc fighting aobut "everything."

Jennifer also spouted the obligatory "I still love my ex" BS ... saying, quote, "I will always respect Marc as a singer and performer. He will always be in our lives. He will always hold a special place in my heart as the father of my children."

MEANWHILE MARC HAS COVERED UP HIS JEN TATT: As peachy and amicable as Jennifer makes their split sound in the "Vanity Fair" interview, Marc didn't even wait for the ink to dry on the divorce papers before ridding himself on his "Jennifer" tattoo with new ink ...

Me thinks there's either some serious heartache, some serious anger, or a new lady in the mix.

WATCH MILA KUNIS CHEW A REPORTER OUT IN RUSSIAN: MILA KUNIS and JUSTIN TIMBERLAKE were in Moscow the other day doing press for the foreign release of "Friends with Benefits", when one of the reporters asked Justin why he's doing movies now instead of music. That, for some reason, set Mila off and she told the reporter off - in Russian, no less!  She said, quote, "Why movies? Why not? What kind of question is that? Why are you here?"

LINDA EVANGELISTA LOOKING FOR HISTORIC CHILD SUPPORT PAYMENT: Supermodel LINDA EVANGELISTA wants SALMA HAYEK'S husband to pay up. It was revealed earlier this year that Hayek's husband, François-Henri Pinault, is Evangelista's baby-daddy as well.

And now Evangelista wants the billionaire to pay her $46,000-a-month in child support. Pinault fathered the supermodel's four-year-old son Augustin James in 2006 when he and Hayek were on a break. According to Evangelista's lawyer, the $46,000 monthly payment would cover 24-hour nannies and drivers, armed with guns. When asked to explain just how busy she is, that she needs 24-hour nannies, Evangelista explained, "On days when I do not work, I am working on my image. I have to hit the gym. I have beauty appointments. I have to work toward my next job and maintaining my image, just like an athlete."
