The Real Housewives of New York City. 9pm on Bravo. The 100th episode is full of drama, as tensions rise in Turks and Caicos between Sonja and the rest of the ladies, who she finds out are talking behind her back. Plus, Dorinda gets into her first-ever argument on the show with none other than Heather.

Kate Plus 8. 10pm on TLC. Last week we celebrated Kate's 40th birthday but this time its the sextuplets' turn, who get a big 11th birthday party filled with pizza, roller-blading, a sleepover, and of course some sibling rivalry, too.

Scream. 10pm on MTV. The TV series based on the movie franchise is finally here! In the pilot, a popular high schooler (played by Bella Thorne) gets murdered, which brings clues to the town about similar murders that happened there 20 years prior.
