Martin Kristen Heidi Klum soccer game

Heidi Klum was radiant Saturday at her boys' soccer game in Brentwood.

Accompanied by her boyfriend Martin Kristen and daughters Leni and Lou, the supermodel mom wore a revealing cream cami top with a black silk maxi-skirt and matching striped belt. She left the makeup at home (uh, yeah; she doesn't need it!) and wore flip flops on a hot LA morning.

Klum and her bodyguard beau were lovey-dovey on the sidelines while Johan and Henry showed off their skills on the field. Our photographer described Heidi's mood as "romantic" and tells us the mother of four doted on her children AND on Martin -- holding hands with her beefy man, rubbing his leg and cuddling up to him while the boys' soccer match was in full swing.

Who can blame her?! She's got a new lease on life with a new man and four beautiful kids ... what's not to celebrate!
