Brittanya O'Campo has learned the consequences of attacking another woman -- again.

The former Rock of Love Bus contestant has been sentenced to six months in jail for a 2008 incident in which she assaulted a woman with a "pimp chalice," TMZ reported Wednesday. 

O'Campo began her sentence at Ventura County Jail in Santa Paula, CA on Tuesday after she pleaded guilty to felony assault with a deadly weapon and misdemeanor battery.

"I will be locked up for 6 months [sic]. I can only get PostCards, no letters or packages," the 25-year-old wrote in a Christmas Day posting to her fans on Twitter.

O'Campo's victim reportedly needed several stitches to close the gashes caused by the blows by the chalice or "pimp cup," a flashy drinking goblet popularized by rappers such as Lil' Jon.

O'Campo, a heavily tattooed brunette with cheek piercings, was one of the final six women competing for Bret Michaels' heart on Rock of Love's third season but was eliminated after she spit and took a swing at first-season Rock of Love runner-up Heather Chadwell and attempted to start a fight with her.

Chadwell and second-season Rock of Love winner Ambre Lake had returned to the show to help Michaels decide which remaining woman was the best match for him and were questioning O'Campo's ex-boyfriend about their relationship at the time.

Rock of Love Bus aired on VH1 in early 2009 and ended with Michaels -- who recently proposed to Kristi Lynn Gibson, his on-again, off-again girlfriend of 16 years -- selecting Taya Parker. 

Chadwell subsequently appeared on Charm School with Ricki Lake, the third season of VH1's Charm School reality franchise, where she finished fourth. In addition, she also competed on the fourth season of the network's I Love Money reality competition, finishing sixth.
