urx unit loader Jennifer Lopez's, Marc Anthony's not so funny Valentine

Jenniferl_leste_56336657_600 Insiders tell the New York Daily News that Jennifer Lopez’s and Marc Anthony‘s tempestuous relationship will explode right after Valentine’s Day.

“Marc and Jennifer are planning on announcing their divorce right after Marc’s show at Madison Square Garden on Feb. 14,” a friend of the couple tells the paper.

“Jennifer is planning to join Marc onstage for a surprise duet. Things haven’t been right for a while now, and they thought it would be a bittersweet farewell."

Who’s surprised? JLo (ta-da!) finally revealed her pregnancy at a sold-out Miami show during her "El Cantante" tour in November 2007.

The couple, married a bit more than four years, are the parents of 10-month-old twins Max and Emme.

Lopez, 39, drew attention to the marital- problem rumors when she arrived looking hotter than she has in years at “The Curious Case of Benjamin Button” L.A. premiere, without her wedding or engagement rings.

And why do we have a feeling that she may end up a presenter at the upcoming Golden Globes awards?

Just call it a hunch.

And there will probably be an attention-getting Versace dress — like her sheer green Versace gown worn to the 2000 Grammys when she was with P Diddy — to get the fashion headlines.

Marc, 40, has been spotted sans his wedding band at N.Y.C. clubs such as Bungalow 8. He was also seen partying without that bit of jewelry with pal Eva Longoria Parker at Lavo in Las Vegas in early December.

Meanwhile, Jen’s ex, Ben Affleck and his wife, Jennifer Garner, are more solid than ever and expecting their second child.

Nyah, nyah.
