4. Paul Rudd and Jimmy Fallon's "Tonight Show" lip-sync battleDoes Paul Rudd never age? Or get less charming? The actor stole the show when he faced off against Jimmy Fallon in a lip-sync battle on "The Tonight Show." We have to admit, he does a pretty great Freddie Mercury:
5. "Survivor: Cagayan" premieres

7. "The Bachelor" hometown dates
Juan Pablo Galavias narrowed his prospects down to four women -- Nikki, Claire, Andi and Renee -- and went to visit each of their hometowns and meet their families this week on the first of two "Bachelor" episodes. Sweet single mom Renee was sent packing, and there was a major dose of drama during the following night's episode when the group went to St. Lucia and Andi quit the show after what she called a "nightmare" evening in the Fantasy Suite. According to her, Juan Pablo never asked her anything about herself during their night together, name dropped and talked over her, said she was there by "default" and told her about his overnight date with Claire.
8. Robin Thicke and Paula Patton split
The "Blurred Lines" singer and his actress wife made headlines when they announced they had separated after nine years of marriage. The couple, who met when they were teenagers, have a 3-year-old son. Thicke took to Facebook this week to thank fans for their support and told the crowd during one of his concerts, "I'm just trying to get my girl back."
9. Paula Deen compares herself to Michael Sam
In an interview with People, Dean said she identified with Sam, the NFL's first openly gay prospect. "I feel like 'embattled' or 'disgraced' will always follow my name. It's like that black football player who recently came out," she told the magazine. "He said, 'I just want to be known as a football player. I don't want to be known as a gay football player.' I know exactly what he's saying."
10. BET's "Being Mary Jane" finale
Fans of the Gabrielle Union-starring drama "Being Mary Jane" got to see the show's two-hour season finale on Tuesday night, when the Union's talk-show host character, Mary Jane Paul, decided to right the wrongs of all the people she's hurt. That's not the last viewers will see of her, though -- the show's already been renewed for a second season.
