Heidi Klum's daughter has grown up and looks like mom

The supermodel's daughter celebrated her birthday recently, and the mother-daughter duo stepped out in style together.

Heidi Klum's daughter, Leni, turned 14 on May 4, and was seen out and about with her mother and as they enjoyed the special day in West Hollywood the following day.

As reported by Daily Mail, Klum decided to go casual for the occasion, opting for a double-denim look. Of course, she pulled it off

Klum wore a pair of heavily torn jeans that were rolled up at her ankles, a plain white t-shirt, and a loosely-hanging denim shirt. She completed the look with a pair of mid-Converse All Stars, and a pair of aviator sunnies.

Continuing the casual look, the 44-year-old left her hair hanging loose around her shoulders.

Klum and Leni had clearly been swiping the credit cards, as she was carrying a bag of goodies in her one hand.

Leni's birthday celebrations started on the Friday night, when Klum and her ex-husband, Seal, took the teenager out to dinner at Matsuhisa in Beverly Hills. They were accompanied by a friend of Leni's.

Sticking to the denim theme, Klum chose a pair of loose-fit jeans with inserts down the sides, a red shirt, and a denim jacket. She added a pair of strappy heels, and left her hair loose.

Leni wore a strappy grey cropped top, a pair of skinny jeans, and a pair of nude pumps. Her friend also went casual for the occasion, wearing a pair of ripped jeans, strappy black cropped top, and a cropped white jacket.

Seal is not Leni's biological father. That falls to Formula 1 team manager Flavio Briatore, but he and Heidi split soon after she fell pregnant with Leni.

The teenager has only ever known Seal as her father, and the Kissed By A Rose singer officially adopted her in 2009.

The singer seemed to be enjoying the evening just as much as the birthday girl, walking a bit ahead of Leni, Klum, and Leni's friend to snap pictures of the trio.

He opted to go as his usual rocker-self, wearing a pair of black skinny jeans, black boots, a white v-neck shirt, and a black jacket.

Seal and Klum also share three other children, sons Henry, 12, Johan, 11, and daughter Lou, 8.
