Robert Pattinson is not the only talented one in the family. His sister, Lizzy Pattinson showed off her vocal chops on "the X Factor UK" instead of asking his brother to give her a free pass to the industry. Knowing who Robert Pattinson in Hollywood, it could be possible. Lizzy never thought of it and does not even want to be associated to Robert, at least when it comes to her venture towards fame.

The Mirror reports that Lizzy Pattinson, the 31-year-old sister of "Twilight" star Robert Pattinson, 28, demonstrated a very impressive performance during an audition for "The X Factor UK," a singing contest produced by Simon Cowell.

"She blew them away with her husky, soulful vocals," said the source, adding, "She's different to usual 'X Factor' contestants, she really stands out."

This is not the first time that Lizzy dabbled on anything big. She also lent her vocals to the first "Twilight" film's motion soundtrack in 2008. She certainly has a shot on this singing competition.

"She could go all the way," another source added.

Asked if she name dropped anyone during the audition, the source said Lizzy would not dream of it.

"She didn't mention she was related to him to any judges or producers," a source said. "It's important to her she does not fall into the trap of just becoming 'Rob's sister.'"

Whether Lizzie will make it or not is still up in the air. However, she should be happy that Robert is an actual fan of the show. If she gets in, she'll have her brother's support for sure. The "Twilight" actor has previously revealed he is really a fan of the show.

"I knowThe X Factor goes against my musical beliefs and I shouldn't love it - but I do, I really do! I am borderline obsessed with Simon Cowell shows and spend my nights in bed watching them on my tablet," shared Rob to the Mirror.

In other RPatz related news, the "Twilight" actor has really and finally moved on from the cheating scandal that he was embroiled in years ago where he was the victim and his then girlfriend, Kristen Stewart the cheater. On a recent interview with Esquire UK, Robert claims that it is not a big deal anymore.

"S--t happens, you know?" the "Twilight" star laughed. "It's just young people...it's normal! And honestly, who gives a s--t?"

"The hardest part was talking about it afterwards," shares Robert. "Because when you talk about other people, it affects them in ways you can't predict," he says. "It's like that scene in Doubt, where he's talking about how to take back gossip? They throw all those feathers from a pillow into the sky and you've got to go and collect all the feathers."
