I was totally thinking the same thing last night as I was watching The District. Jean Smart was guest starring and I was like 'she's my sister'. And of course I have to brag about it every moment I get.
My mom was like 'you just like her because of Scarlett' (the mini-series that she starred in back in like 1995 I think) and I'm like 'yes, I like her because of that and Sweet Home Alabama but mostly because she's my sister.'
