Jim Carrey was serenaded by 50 Cent on his birthday. The "Yes Man" actor and his girlfriend Jenny McCarthy were watching the rapper perform on Saturday when 50 spotted them in the crowd and asked Jim to join him on stage in Park City, Utah.
A source said: "Jim and Jenny were dancing and really getting into the music, so 50 decided to bring him out to the balcony for a special rendition of 'It's Your Birthday.'" "When Fiddy told the crowd, 'I have a very special guest for you,' everyone was floored because he had just done a duet with Robin Thicke. They thought the surprises were over.
