Shauna Sand, ex wife of actor Lorenzo Lamas, was arrested late last night after getting into a fight with her new 25-year-old husband, Laurent Homburger.

A neighbor reported a fight at Sand's home and the Beverly Hills Police Department responded. When officers arrived, we're told they saw marks on Homburger, and Ms. Sand, 39, was arrested for felony domestic violence.

Homburger was also arrested for spousal battery and making criminal threats. Both were booked at the Beverly Hills Police Station. Shauna has been bailed out, however Homburger is still there.

Ironically just yesterday, we snapped the above photo of Shauna grabbing some goodies at the Sugar Factor in the 90210. We have a feeling none of that sugar was for Laurent.

See the couple flashing their wedding rings just a few months ago during happier times ... after the jump.
