Malin Akerman's son has started to say swear words.

Speaking to E! News, Malin explained: "He's walking and talking and he said his first F-bomb. We were watching 'Dolphins.' We were in Vegas at one of the hotels. I don't know where he got it from.

"He must have heard it somewhere but he's a sponge now. He said it about five times in a row with a lot of passion. I just laughed. He's too young. I'm going to be very careful what I say."

However, despite trying to stop Sebastian from spitting out naughty words, the 36-year-old star admits she is loving being a mother to the little one.

She said of parenthood: "I love it. It's one of the best things. What mum are you going to ask and she goes, 'Oh it sucks.' It's unbelievable. It's the biggest love you've ever felt in your life.

"It's scary and it's crazy and some days I wake up and go, 'My god, I'm a mim. I'm responsible for someone's life. What! Who gave this child to me?' "
