Brad and Angelina reportedly spent the special day with friend Sean Penn.

A source told UsMagazine.com that Sean visited the couple at their Los Angeles home on Sunday.

No doubt the actors were using this romantic day to discuss important issues close to their hearts; the Haiti disaster.

It seems as if lending their support in times of humanitarian crisis is one thing the three have in common.

This may have not been the biggest love-in though. Sean, through ex-wife Robin Wright Penn, became good friends with Brad's ex Jennifer Aniston a few years back.

And perhaps Sean was trying to wreak some revenge on Brad and Angelina. According to X17, when he left the Jolie-Pitt compound, Sean was in such a rush that he bashed into the gates with his car.
