Robert Pattinson, Kristen Stewart, Simon Cowell, FKA Twigs & Lizzy Pattinson: 'Twilight' Stars Set For Dating Reunion As Rob Helps Sister Push To Win British X Factor

Robert Pattinson is a very busy man, so it would seem. The star is dating FKA Twigs, while rumors have emerged suggesting he is close to reuniting with former flame Kristen Stewart, who he starred in Twilight with. On top of that he has been giving his sister, Lizzy Pattinson, the vital advice needed to impress Simon Cowell, and help her with her push to win the British X Factor. Can Pattinson focus on all of this and still give his best effort to his career? Can his sister add to the Pattinson legacy?

There are rumors suggesting that Robert Pattinson is using his new relationship with Twigs, born Tahliah Barnett, to make Stewart jealous and to get her back. An insider told Hollywood Life that "Kristen knows about Rob and Tahliah. It's bittersweet. I mean she's happy that he's happy, but it stings. She knows it must be serious if he's being affectionate with her in public. She knows he's ultra picky and wouldn't hold hands with someone for the world to see unless he was really into her."

Could they get back together? For now he's focusing on his sister, who is trying to win the X Factor. She has kept her famous brother out of the limelight, but she admitted she got his advice. She explained, "I sent him a link to the songs for the Judges' Houses and he said, 'They sound really cool.' One of the songs was quite obscure and he thought it was really good. I am surprised how interested he is in it. He watched the first episode I was in. He gave me feedback and that meant a lot to me."

Can the Pattinson family rule the entertainment world, and will he sort out his dating life once and for all?
