Kelis has filed legal papers demanding her ex, Nas, give her some dosh towards their unborn child.

According to reports, the wayward rapper has so far paid the princely sum of absolutely nothing, while cash-strapped Kelis has just announced: “I have run out of money.”

The bling-lovin' R&B babe ain’t taking it lying down, however.

The 'I Hate You So Much Right Now' gal is demanding Nas pay spousal support, child support, all pregnancy-related expenses, and one-half of all medical expenses after the child is born. Plus, she wants an extra $US 3,500 for a nurse and $US 20,000 for prams, nappies and all that other newborn baby paraphernalia.

Kelis told TMZ.com: "My survival is based on Nas's will at this time. If he does not want to pay for an expense, it does not get paid."

Hmm... You have a choice of paying up or packing your bags, Nas, 'cos if you don't you'll be going on one long guilt trip.

But we’re glad to report that preggers popstrel Kelis is keeping her pecker up in the face of her cash probs, nevertheless.

In recent Twitter activity, she Tweeted: “Don't really sleep great, 5 weeks and 3 days count down people. I can't wait! I am so tired of this preggy body its exhausting!”

Atta girl.
