Blind Item #8

This celebrity/reality brother and sister team got into a huge fight this week because the sister was jealous of one of her brother's most recent conquests. He slept with one of her girlfriends and she was jealous. I don't understand because she is not bisexual or a lesbian. So, the only reason she could be jealous is if she wanted her brother all for herself? Eww. especially eww when you know who I am discussing.
