Teen Mom star and son in serious car crash

MTV reality star Maci Bookout had a lucky break at the weekend as she and her young son Bentley walked away from a serious car wreck without any major injuries.

The 23-year-old, who is currently pregnant with her second child, shared four photos of the crash, which occurred when her Jeep skidded and overturned on a busy road.

The vehicle rolled over three times but luckily both Maci and 6-year-old Bentley escaped with just a few bruises and no complications.

The scary images which Maci shared on Instagram were captioned, "Thanking God that my unborn baby girl is perfectly healthy after this. I'd also like to @JeepOfficial @Jeep because if our seatbelts and the roll cage had not done their job, I'm not sure my family and I would of had the same outcome. Thanks to everyone that stopped to help, that was huge. I pray everyone else involved is doing okay. #jeepwrangler #rolledthreetimes #terrifying #totaled #notmyfault."

The crash comes just one month after Maci's ex and Bentley's father Ryan Edwards was injured in another car crash which left him in a neck brace.

Maci is best known for her work on MTV's Teen Mom, on which her and Ryan appeared together. The pair split in 2009 after a brief engagement, and Maci announced her prgenancy with new boyfriend Taylor McKinney shortly before Christmas.
