Heidi Klum Lou Henry Johan Martin Kristen

From supermodel to supermom!

Heidi Klum spent the day before Mother's Day with her beautiful brood. She took her daughter Leni and three of her adorable friends, who sported matching brightly colored sequined tanks, ra-ra skirts, and bike shorts, to a soccer game. The girls and Heidi's boyfriend Martin Kristen watched from the sidelines and cheered on as Heidi's boys Johan and Henry played soccer.

After hanging out at the park in Brentwood, the gang headed to Santa Monica for some more fun in the sun. The kids and their soccer buds biked around the beach before going to Venice's famous Muscle Beach to play with exercise equipment.

Heidi recently told Us Weekly that it's difficult to balance her busy professional life and her personal life. After giving the interview, she added America's Got Talent judging duties to her already heavy load.

"It's a huge responsibility to have four kids," she said. "They all have different likes and dislikes and activities that they want to do. You have to learn how to juggle all of that, and at the same time, give them each the love that they need. ... When you have one [child], you can focus on one. With four, you have to make sure [your attention] is all spread out just right. You have to understand how different they all are! And at the end of the day, there is not much time left for you!"

She certainly found activities for them to do on Saturday.
