A pregnant woman who used a bogus credit card to steal from a Sephora makeup store was killed when her baby daddy drove their getaway car the wrong way on the Long Island Expressway, police said Monday.

Six-months-pregnant Demytrya Gibbs, 27, and accomplice Khadisah Green, 23, pulled off the theft in Manhasset around 3:40 p.m. Sunday, according to authorities.

The women then hopped into a 2013 Hyundai Sonata driven by Gibbs’ boyfriend, Courtney Corbett, 28, authorities said.

Corbett drove the wrong way onto the LIE’s south service road near Exit 34 in Manhasset and crashed head-on into another car, police said. Gibbs and her unborn child were killed.
