Chris Rock doesn't know what is next after his divorce.

The 50-year-old actor has revealed he worries about what will happen when his daughters grow up after his divorce from his wife of almost 20 years, Malaak Compton-Rock.

Chris opened up to The Guardian newspaper: ''Can I keep it going and raise healthy daughters who don't have daddy issues because I'm gone all the time?

''So who the hell knows what's next.''

The comedian split from his wife - with whom he has daughters Lola, 12, and Zahra, 10 - in December, and admitted although he is getting his life back on track, he is riddled with fears about his children.

He revealed: ''I'm doing OK. You know, some days are better than others, some days you're sad outta your f***ing mind. But my daughters are good and I'm only an hour away. Two houses close by. It's good.''

However, the 'Top Five' star said he has been hitting the gym since their split in a bid to gain a more buff physique to woo a potential partner.

He said: ''I work out now, because you have to when you're single ... but I'm still skinny.''
