This was quite the birthday party.

Ellen Degeneres celebrated her 53rd birthday in style on Wednesday, bringing the party to her show. Julia Roberts stopped by with a necklace, while Colin Farrell brought in a birthday cake that she'll need years to eat.

Perhaps she'll get help from wife Portia de Rossi, though she was showing quite the figure dressed up as Marilyn Monroe. Check out the video of de Rossi's singing to Ellen, JFK-style, below.
