He's the nicest guy in Hollywood!

Chris Martin was bombarded by fans wanting pictures and autographs while out and about on his 40th birthday in West Hollywood, and the rocker took the time to stop and grant each one's requests. Remind us why Gwyneth Paltrow ever divorced him again?

The actress still has fond feelings for the father of her children, through, and took to Instagram to send well wishes on his special day. "HAPPY 40th BIRTHDAY to the best daddy in the world!!! We 💖you so much!" she captioned a photo of their family.

They might not be together anymore, but the Oscar winner knows just what a good man he really is.

"To this day, Chris would take a bullet for me, even though I'm not his wife. I honestly think Chris and I have contributed something positive to the culture of divorce. He's at my house every single day. We have our own lives, but we still have our family life," she told InStyle in February.

We couldn't love the Coldplay front man more if we tried!

HAPPY 40th BIRTHDAY to the best daddy in the world!!! We 💖you so much!
