Jamie Lynn Spears' fiance Casey Aldridge was filmed threatening a photographer attempting to take a picture of the couple, it has been reported.

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.                                                                                                         

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.// Bang! Showbiz
