Jennifer Lopez and her husband Marc Anthony are planning to announce their separation in February, according to new reports.

The couple - who renewed their wedding vows only three months ago - are said to be going through a tough time and have reached the point of no return.

Jennifer and Marc were stronger than ever this time last year - with Emme and Max on the way - but parenting twins seems to have taken its toll.

A source tells the New York Daily News' Gatecrasher column, "Marc and Jennifer are planning on announcing their divorce right after Marc's show at Madison Square Garden on Feb. 14.

"Jennifer is planning on joining Marc onstage for a surprise duet. Things haven't been right for a while now, and they thought it would be a bittersweet farewell.

"They're definitely planning a clean break in February."
