Jamie Lynn Spears' boyfriend pulls gun on photographer

Jamie Lynn Spears' fiance Casey Aldridge pulled a gun on a photographer attempting to take a picture of the couple.

The 17-year-old star - who is expecting her first child with Casey - was filmed driving along a dirt trail in an all-terrain vehicle in Kentwood, Louisiana, with 18-year-old Casey when he started shouting at a photographer who, he alleged, was trespassing on private property.

The video from gossip website tmz.com shows Casey brandishing what appears to be a gun or another form of weapon from his pocket when the photographer refuses to leave.

Casey and Jamie Lynn then drove off. Jamie Lynn is reported to be expecting a baby girl after she was spotted loading a pink baby carrier into her vehicle.

Following reports Casey proposed to the 'Zoey 101' actress earlier this month, Jamie Lynn wore a T-shirt bearing the slogan 'The Rumours Are True' and showed off her diamond engagement ring.
