Gwyneth Paltrow has joked her children look "alien" to her.

The Hollywood actress has daughter Apple, eight, and son Moses, six, with her husband Chris Martin. When asked which part of herself she sees in her kids, Gwyneth replied "nothing" - explaining that physically Apple and Moses don't take after either of their parents.

"It's all alien! I don't think they look like us at all. Sometimes I see behaviours that reminds me of us, but physically I can't see it!" she quipped in an interview with the UK edition of OK! magazine.

Gwyneth has previously said that she wants to put her family before any leading roles. At the moment, the 39-year-old star finds juggling her Hollywood life with parenting possible.

"When I first had my kids, I just did not want to be anywhere else. They're only little for a few more years and I don't want to miss out on it. When it's gone, it's gone. In five or seven years they'll be like, 'Mom, get out of my room, I want to be with my friends," she laughed. "But now that they are older, I feel like my sense of self is coming back as an artist, so it's harder.

"But I figure everything is meant to be and if Meryl Streep is still doing roles, maybe I'll be so lucky to get a good part like that later in my life."
