J-Lo wears a slinky white gown and blonde wig and serenades the host of 'Lopez Tonight' on April 22, a day before he turns 49.
Jennifer Lopez helped make her pal George Lopez's birthday extra special - by dressing up as Marilyn Monroe to serenade the comedian on his talk show. The actress helped the funnyman, who turns 49 on Friday, April 23, wrap up his birthday episode of "Lopez Tonight" on Thursday, April 22 by stepping out in a slinky white gown and blonde wig to sing Happy Birthday.
She told Lopez, "I wanted to do something special to surprise you. Calm down, birthday boy, take a seat and let me do my thing."
Earlier in the show, Lopez challenged Jennifer to disprove her high maintenance reputation with a 'Not A Diva' showdown - in which the two Lopezes competed to see who was the fastest at making a sandwich, bagging groceries and changing babies' diapers.
