Jessica Alba ''loved'' being asked for her ID on a recent night out.

The 34-year-old actress was reportedly asked to prove her age as she enjoyed dinner a Korean restaurant in Los Angeles with husband Cash Warren, and appeared delighted that the waiter thought she was younger than her years.

An eyewitness told Us Weekly magazine: ''When she ordered something to drink, the server asked to see her ID. And nobody else was asked for theirs. She totally loved it!''

A pal of Jessica's says her youthful glow can be credited to her use of organic beauty products created by her billion-dollar brand, The Honest Company.

The friend said: ''She loves being told how young she looks! And she uses all of her own products so it's an extra compliment to her.''

The 'Barely Lethal' actress admitted earlier this year that she struggled with turning 30.

She said: ''I was really sad when I turned 30. I still wanted to party like a rock star.''

However, Jessica, who has two daughters -- Honor, seven, and Haven, four -- is feeling much more confident as she gets older.

She explained: ''I'm more comfortable in my own skin than I was before. I think you just have a different mentality on what really matters, the older you get. I feel better than ever!''
