Marc Anthony had 'Happy Birthday' sung to him by President Barack Obama.

The singer - who turned 41 on Wednesday (16.09.09) - and his wife Jennifer Lopez were in Washington D.C. for the Congressional Hispanic Caucus Institute's Awards Gala, which the US leader also attended.

Jennifer Lopez has kept $50,000 worth of diamonds she borrowed last week. The singer-and-actress wore the Robert Mouawad jewelry to the launch of Andrea Lieberman's fashion line ALC, in Beverly Hills, and while other guests have given back the precious jewels, Jennifer has kept hers.

A source told the New York Post newspaper: "We received a call from her manager informing us that Jennifer was going to keep the jewelry. As far as Mr. Mouawad is concerned, Jennifer can have whatever she wants, but a premature demand seemed presumptuous.

Jennifer Lopez is reportedly starting a new career as a TV and film producer. The "Get Right" star is set to take a break from her 10-year music career to get some "professional distance" from Marc Anthony, the Latin singer she married in 2004.

A source told MSNBC: "Jennifer hasn't been able to be considered a real recording success since she's been with Marc. No matter how hard she tries, she can't go back and be Jenny from the Block."

Jennifer Lopez says divorcing her husband is "not an option." The singer-and-actress has been dogged by rumors her four-year marriage to musician Marc Anthony is on the brink of collapse, but insists the reports are wide of the mark.

She told In Touch Weekly magazine: "Every time I'm not wearing my ring, people think I'm getting divorced. Divorce is not - and was never - an option."
