'Friends' Joey's sister is pregnant.

I DO NOT OWN. From 'Friends' Season 8. The One with Monica's Boots.
Joey is upset that his sister got pregnant and is trying to make it right.
Update: Since there seems to be a lot of confusion in the comments, this is Dina played by the lovely Marla Sokoloff. The sister that appears in the Spin-off "Joey" is Gina....
When it comes to Joey's sisters...
In the episode in which they all appear (Season 3 Episode 11 - The One Where Chandler Can't Remember Which Sister") there are 6 mentioned by name that I noticed - Gina, Dina, Veronica, Mary Angela, Mary Therese and Cookie. According to the IMDb entry for that episode, there is also a Tina who, as far as I know, is only confirmed of in 'Joey' Season 1 Episode 19...also, in this episode Mary Therese's name is suddenly changed to Mary Teresa.
Hopefully that clears things up for some of you.
