White also used his Instagram page to wish the love of his life a happy birthday. The actor shared a photo of a door filled with several mementos of the couple's relationship.

From sweet photos together and nights out with friends to the love letters and poems shared between them, everything could be found stapled to the door.

But there was something more there; among all the pictures, including ultrasounds, there was also a Mother's Day card that, and in the caption, White wrote 'You're gonna be the best momma, I love you.'

Last year, in honor of Timlin's birthday, White, who also starred in Law & Order and Rob the Mob, posted a picture of his girlfriend wearing only a small top and bikini bottoms, describing her as his 'hero.'
