Johnny Depp marked his recent 50th birthday with a low-key dinner with his children because he feels celebrating big milestones is like "clinging to vanity".

The Pirates of the Caribbean star reached the big 5-0 on 9 June (13), but instead of a party he opted to dine out with his 14-year-old daughter Lily-Rose and son Jack, 11.

He tells Britain's Daily Mirror, "We kept it simple and we just went to dinner. I find the whole idea of celebrating one's birthday is like clinging to vanity in a way, which is something I'd rather not cling to.

"It's one of those things. It's another decade... Cool. I didn't suddenly wake up and go, 'God, my back is killing me!'"

Lily-Rose and Jack are Depp's children with former partner Vanessa Paradis, who he split from last year (12).
