(BANG) -Matthew McConaughey's daughter Vida is ''sassy''.

The actor has two children, son Levi, four, and Vida, two and is expecting a third with his handbag designer wife Camila Alves and she says Vida is full of personality.

Camila explained to Usmagazine.com: ''They're at that stage where every day, there's something new. Vida has more personality than I can explain to you! She's very sassy. It's great.''

Camila also revealed the youngsters are excited about a new sibling.

She said: ''They love [my baby bump]. I think they fully understand that it's a little baby coming. They love it.''

The 29-year-old beauty recently admitted carrying her third child is much ''different'' to when she was expecting her other two kids and she has found it more difficult.

She said: ''This [pregnancy] has been a little different.

''Anything you can feel in a pregnancy, I'm feeling in this one. So put it all in the pile, that's how I'm feeling.''

However, Camila is not yet experiencing any unusual food cravings.

She added: ''We have gone the complete opposite direction eating wise, but we're navigating it. But I don't really have cravings yet.''
