Gwyneth Paltrow has defended Kim Kardashian against jibes about her weight.

The reality TV star is expecting her first child with boyfriend Kanye West and has been the subject of ridicule for her weight gain, leading mother-of-two Gwyneth to stand up for her.

She told ET Online: ''I think that women should support each other, especially through pregnancy, it's a difficult time and I think Kim Kardashian looks absolutely beautiful.

''And we're supposed to gain weight when pregnant -- that's how God intended it.''

Molly Sims also showed her support for Kim, saying: ''I love that she has embraced it and that she is still wearing whatever she wants to wear. I'm kind of jealous. I like it.''

Although stars such as Jon Hamm and Daniel Craig have previously blasted Kim, 32, for being too open about her private life, Gywneth and Molly aren't her only celebrity supporters.

Jennifer Aniston previously revealed she is a fan of Kim, although she insisted they have nothing in common.

She said: ''There's nothing wrong with Kim Kardashian and all those people.

''If that's how they choose to make a living, more power to them.

''My line of work is different. I want to entertain people.''
