It looks like Nicki Minaj and Mariah Carey are still throwing major shade towards each other. On Wednesday night's (May 1st) episode of American Idol, the two constantly threw jabs at each other. Perezhilton wrote about their shady exchanges, saying that Mariah "burned" Nicki when she bragged about having so many number one hits. Nicki must have read Perez's blog post, because Nicki wrote to him via Twitter, "Bwaha! Burn? Shes sad i tied her record for Hot 100 entries in only 3 years of being in the game. Yep, a black female rapper." She then added, "What u SHOULD be doing (wit your messy a**) is asking why a woman SO successful at her age, is still so INSECURE, and bitter."She then threw some more shade towards Mariah, tweeting, "All dem #1s but JLo phone ringin? Lol. I guess having a personality, being a secure woman, and giving genuine critique still trumps that." Perez continued stirring the pot, tweeting, "@MariahCarey Hey, Mimi! @NICKIMINAJ just called you sad, INSECURE and bitter."Nicki Minaj ✔ @NICKIMINAJ Bwaha! Burn?

Taylor Swift will be a guest star on the season finale of the FOX sitcom, New Girl. She recently shot the episode, and cast members were impressed with her acting abilities. Taylor plays a wedding guest named Elaine, and according to Jake Johnson, one of the stars of New Girl, her talent was "a little bit frustrating." Jake told Entertainment Weekly, "She came in and is really nice. It's not an easy scene. There were probably 70 extras there -- though I'm sure she performs to so much bigger (crowds) than that on a regular basis. She had, like, a little monologue and delivered it perfectly. (Producer) Liz gave her alternative jokes and lines, she delivered them all perfectly. It was frustrating!"According to the producer, Taylor did "a little bit of a riff on one of her songs."The season finale of New Girl featuring Taylor airs on May 14th.Taylor's previous acting gigs include an episode of CSI, the movie Valentine's Day and the voice of one of the characters in The Lorax.

She says, "Ryan Gosling is such a given, but he's super-cute. I've not met him yet. I've seen him on an airplane... and I didn't... I freaked out so I didn't even... I don't even think he saw me, so... But that one."

A source says, “Amanda is also extremely paranoid and thinks there are tracking devices in the smoke alarms in the apartment. She looks completely disheveled. Her behavior is “disturbing” but her parents can’t do anything to help her. There are no legal options available to them to help rescue their daughter at this time.”Amanda Tweeted: "All I want is a boyfriend who wants us to grow old and to get fat together." AMANDA BYNES CLAIMS TO HAVE OLSEN MONEY: Amanda Bynes recently told In Touch, "I'm in the Mary-Kate and Ashley type of wealth category" but sources say she is worth far less. An insider told the magazine that she is worth a lot less than the Olsen twins and that her spending is out of control from $11,000 hair extensions, month-long stays at luxury hotels and huge cab fares. The source added, "She's going to run out of money sooner or later. The girl no longer has an income."

A source tells the Sun,' 'Katy believes the workouts have really helped her with releasing anger, stress and tension from the split and the sanctuary has been soothing her brain. 'A few years ago she would have released the energy by hitting the clubs and dancing the night away. But she's getting older now and wants to do things healthily.''

"I just wanted to document my life, because it''s so insane; I wanted somebody to catch it on film, so I can watch it when I''m old and saggy and be like ''My life was so crazy!'' What you get in the show is real; it''s not scripted or... thought out at all. It''s just my life. It''s very real and honest."

Mariah threatened to sue. Nigel Lythgoe says, "I have not been included in any conversation regarding replacing Mariah with Jen this season." The Hollywood Reporter claims all of the judges may get replaced.

A source tells RADAR Online, "Everyone thinks that Mario hated working with Khloe. But he was nothing but encouraging and supportive (to Khloe). It was her mother Kris who was the problem. Kris would go to the producers and say Mario was being pushy and insensitive and she’d often confront Mario directly. There was even a very absurd incident when Kris suggested to the producers that they should dump Mario and replace him with one of her other daughters. Kris claimed that the chemistry between Mario and Khloe just didn’t work and that Kim or Kourtney would be a better fit. Well, the producers agreed with the no chemistry argument, but also that Khloe was in over her head – and that’s why she’s gone.”
