Talk about hitting somebody below the belt.

In a recent promo for The Real Housewives of Beverly Hills' second season, Camille Grammer takes a jab at her ex-husband Kelsey Grammer's manhood.

"Big hands, big feet, big disappointment," Camille says in the clip, alluding to 46-year-old Kelsey's penis size.

When asked by TMZ to elaborate, 42-year-old Camille confirmed that the comment was indeed about her ex-husband. "I had that for 13 years, unfortunately," she explained.

Things have pretty nasty between Kelsey and Camille, who are both seeking primary custody of their two children, Mason, 9, and Jude, 6. After 13 years of marriage, the couple's divorce was finalized on February 10. Kelsey wed flight attendant Kayte Walsh 16 days later in New York City.
