David Beckham sweetly admits to getting 'physically ill' when he has to leave his children

David Beckham is easily known as one of the hottest dads in Hollywood, and also one of the sweetest.

The former soccer player appears in the April issue of GQ magazine for what might be his sexiest, most stylish photo spread yet. In addition to impressive modeling skills, Beckham is also pretty vulnerable when asked about his personal life and the four children -- Brooklyn, 17, Romeo, 13, Cruz, 11, and Harper, 4 -- he shares with Victoria Beckham.

"I get physically ill when I have to leave the kids now," the 40-year-old heartthrob reveals. In his spare time, Beckham says he can usually be found watching "Frozen" with his daughter for the hundredth time or binge-watching "Friends."

As for his glory days on the soccer field (he retired in May 2013), Beckham doesn't seem quite done with the game. "I miss soccer every day. I don't know whether it's the athlete in me, or the passion I have for the game: I always think that I can step back on the field and play," he touts. "You know, maybe I could play another year in the U.S. if I was still living in L.A. I'd probably really seriously think about coming back for a year, but we're living in London and the kids are happy in the school."

Beckham is already pretty busy divvying up his time between his family and modeling career obligations -- but just wait until Harper hits high school! When ET caught up with him in January, Beckham admitted that the dating rules in his house will "definitely be different" for his daughter than her three brothers. "I have no power with that little girl -- no power whatsoever," he quipped. "I love all my children, of course, equally but I'm definitely stricter with the boys than I am Harper, which gets me in trouble with my wife of course."
