Uh oh. Not another sisterly argument! We last saw Kyle and Kim Richards in Season 3, Episode 1, "Down and Left Out in Beverly Hills" talking about whether Kim will attend Portia's upcoming birthday party. Kim hints on her Bravo blog that she "always made it a priority to always participate in all my nieces' and nephews' birthdays..."

Watch this video to see why Kim doesn't feel like going, and tune into Bravo tonight, November 12, at 9 p.m. to see if Kim will show up after all.

Do you think she will? Why or why not? Tell us in the comments below!
