She took to Twitter to deny that Louis Tomlinson and his girlfriend Eleanor Calder have split, just as El was spotted in Las Vegas with the One Direction boys!

According to Entertainment.stv.tv, Louis Tomlinson's sister Lottie took to Twitter to debunk rumors that her brother and girlfriend Eleanor Calder had a break up.

She wrote to her followers: "People that make stuff up must be so bored with their own lives that they feel the need to cause problems, so pathetic"

The tweet has been favorited 4.5 thousand times and retweeted 2.5 thousand times.

We know Lottie is telling the truth that this recent slew of break up rumors are all fake: Unreality TV reports that Eleanor Calder has flown out to be with the One Direction boys in the US as they wrap up their "Where We Are" tour. She was spotted in Las Vegas with Louis Tomlinson, Liam Payne, and Niall Horan, having a fun last-minute break before their concert dates resume and finishes up in Miami on October 5.

Louis and his girlfriend have been dating since 2011.

Speaking earlier this year, the 21 year-old admitted Eleanor struggles with the spotlight, Entertainmentwise reports.

"It hasn't been easy at times," he told Fabulous magazine. "She gets pretty intimidated by it all. I mean, who wouldn't? She can't have Twitter or anything like that. At first, I was like, 'Just chill out a bit, it's fine' but now I understand where she's coming from."

"I can't expect her to deal with some of the stuff so easily. But with that said, I couldn't be happier with her," he added.

"Things really bother me when they upset my family or Eleanor," Louis explained. "I think I'm quite thick-skinned but if you're going to do or say that, f*** you."
