Louis Tomlinson's girlfriend Eleanor Calder will join One Direction on their tour 2014, reportedly to keep watch over Louis after he and fellow band mate Zayn Malik were caught in the recent smoking weed video scandal. Zayn Malik's fiancee Perrie Edwards is also "really worried" about her soon-to-be husband. Are the One Direction boys "out of control"?

According to UnrealityTV, Heat magazine reports that Louis Tomlinson and Zayn Malik are partying too hard, and now their girlfriends Eleanor Calder and Perrie Edwards are starting to worry that it is affecting their commitments to One Direction and their 2014 tour.

"There was a massive showdown in South America recently and management warned them they were acting too wildly," a source told Heat.

"There was [also] an incident in Santiago where Louis and Zayn partied all night and only had two hours of sleep before performing.

"There's hardly a day [goes by] when one of them isn't late, hungover or in a bad mood.

"This has been spiralling out of control for a long time."

Little Mix's Perrie Edwards and Eleanor Calder are "really worried," the source continued: "They've been on the phone to each other a lot, asking what they can do to stop this behaviour."

According to The Sun, and as reported by Entertainmentwise, Louis Tomlinson's girlfriend Eleanor Calder will join the One Direction tour 2014 to stay close to Louis and keep him out of trouble, following the Zayn Malik smoking weed video scandal.

"There will be sighs of relief all round at this news," the insider said in the report.

"Eleanor is a great influence on Louis, he's always just so much happier when she's around," the source explained. "They are joined at the hip whenever she comes on tour."

This is only possible because Eleanor has finished studying for her degree and has a few months off to travel with the One Direction singer, The Sun reports. Perrie, meanwhile, is likely too busy with her Little Mix commitments to follow Zayn around the world.

As we previously reported, One Direction was rocked with a scandal when a leaked video hit the internet featuring Zayn Malik and Louis Tomlinson smoking weed in Peru, damaging the boy band's image.

The Daily Mail obtained the video of Zayn Malik and Louis Tomlinson in the back of a smoke-filled van in Peru, puffing on what the boys refer to as a "joint." The video has shocked some of One Direction's younger fans.

One Direction's other band mates Liam Payne, Harry Styles, and Niall Horan are not present. It is assumed they were in another vehicle, The Australian reports.
