What a cool and hip mommy!

Heidi Klum, and her sexy beau Martin Kristen, took her kids Leni, Henry, and Johan to see Justin Bieber perform at the Staples Center in Los Angeles.

While the supermodel rocked leather pants, her kids opted for shirts with a photo of the teen sensation.

Looks like lil' Johan had a great time. Good thing the little tot had a strong shoulder to lean on!
