Ray J and his ex-girlfriend are fighting over custody of their little pet dog following their split earlier this week.

The 33-year-old rapper reportedly called time on his short-lived relationship with Princess Love on Thursday (09.10.14), but it wasn't an easy break-up as a huge row broke out over their Maltese puppy, Boogotti.

After calling it quits, Princess - who lived with Ray J -started to pack up her belongings but things took a turn for the worse when she attempted to take the pooch.

A source told TMZ.com: ''The two went at it over the three-pound Maltese puppy, to the point where Ray's security had to step in.''

The hunky singer's security team managed to get Boogotti off the brunette beauty and the four-legged creature has remained in R Jay's custody ever since.

However, it is believed the couple's fight over their dog will continue to go on and will likely feature on their reality TV show, 'Love & Hip Hop: Los Angeles.'

The source added: ''Ray J knows this won't be the the end of the battle.''

Meanwhile, Princess has wasted no time announcing that she's single as she took to her Instagram account yesterday (10.10.14) to post a cryptic quote.

She wrote: ''Not everyone you lose is a loss.''

However, she quickly deleted it and replaced it with a past photograph of herself and ex-boyfriend floyd mayweather.
