Born July 24, 1969, Jennifer Lopez, affectionally referred to as “J.Lo” celebrates her 47th birthday today [Sunday, July 24]. Her American Idol co-star Ryan Seacrest wrote in a post: “Happy Birthday to the only woman I know who continues to age in reverse.”

Lopez got her start as a “Fly Girl” on the television show, In Living Color, in the early ’90s and has gone on to star in dozens of major films. Her music career was briefly lucrative in the late ’90s, but she has since focused more on acting and her fashion line, appropriately called J.Lo. She also has a production company and charity foundation.

After several high profile relationships with actors like Ben Affleck, and marriages to Marc Anthony and Cris Judd, Lopez is now dating Casper Smart, who attended her Las Vegas birthday bash.
