Well boo-f*cken-hoo Liz! Shoulda thought of that...

Liz Hurley has declared single motherhood "sucks" and made a plea for boyfriend Arun Nayar to propose.

The model, who turns 40 in June, desperately wants another child but insists on being married first.

She has brought up her three-year-old son Damian alone following an acrimonious split from his father, billionaire Steve Bing.

"I've been a single mother once and I am sure every single mother in the world would agree with me - it sucks," she told ES magazine.

"As I turn 40, I see marriage very differently. Now, although it's never been something I've thought important before, I can see why it is important for people to declare their intentions, make vows, and make proper, above-board plans for everybody, because that clarifies and simplifies things quite a lot."
