Seal has a reputation for kicking some paparazzi butt — and it appears his kids will soon follow suit.

After spending nearly two hours practicing their kicks, blocks and strikes, Leni Klum and Henry Samuel were seen leaving a taekwondo class in Hollywood today (September 3) accompanied by their adult contemporary crooner father.

As for family matriarch Heidi Klum’s whereabouts? The former supermodel is currently putting the final touches on Rankin’s Heidilicious, a sexy new coffee table book due out in October.

“It’s very naughty, I’ve been shooting with this photographer, Rankin, for seven years and working with him is fun because he always makes me look different,” Heidi tells the September issue of Los Angeles Confidential Magazine. “He always gets me to take my clothes off for some reason. We’ll do some job and then he’ll say, ‘Why don’t we shoot some more things?’ and I’ll wind up without anything on.”

In addition to her literary duties, Heidi has her own beauty line, a new show called Models of the Runway on Lifetime, hosting duties for season eight of Project Runway, and, oh yeah, did we mention she’s eight months pregnant?
