Halle Berry is looking forward to a relaxing Mother's Day.

The pregnant 'Cloud Atlas' star - who is expecting a baby later this year with her French actor fiance Olivier Martinez - is happy to let her five-year-old daughter Nahla, with ex-boyfriend Gabriel Aubry, plan the entire celebration, which takes place in America on Sunday (12.05.13).

The 46-year-old actress told People.com: ''What I love about Mother's Day is Mom doesn't have to plan it.''

Halle admitted she has no idea how Olivier and Nahla are planning to spoil her.

She said: ''I don't know what it is. My family gets together and they get to plan the day for me, and I love that. I'm the planner and I'm the one that organises. And on Mother's Day I get to just be taken care of.''

The actress is feeling great during her second pregnancy but insisted she doesn't know the sex of her baby yet.

She said: ''We don't know what we're having. We're having a baby, that's for sure.''

Halle, who has been divorced twice, recently insisted she can't wait to tie the knot with Olivier.

She said: ''Absolutely. I'm an incurable romantic - that's the only reason I'm marrying again. Just because things haven't gone well in my past doesn't mean that I've given up.''
