Troubled country star Mindy McCready reportedly discovered she's pregnant while in jail for violating probation.

The singer was arrested last week (26AUG05) for violating her probation from a drug conviction and discovered she's with child, according to US tabloid National Enquirer, after a medical check-up at the Pinellas County Jail in Florida.

It isn't known who the father is but McCready is reportedly back in the arms of ex-boyfriend Billy Mcknight, who she charged with attempting to beat her to death earlier this year (05).

McCready has had a controversial summer (05) - she was charged with identity theft, arrested for drink-driving in May (05) and she attempted suicide in July (05) by taking an overdose of prescription pills.
