Louis Tomlinson Saves 15-Year-Old Sister Lottie From 24-Year-Old Twitter Creep Sending X-Rated Texts

Though Louis Tomlinson is a bit busy these days with the One Direction "Where We Are" 2014 world stadium tour (and a recent leaked video featuring him and Zayn Malik smoking pot, saying racial slurs), he definitely has time to be a great big brother. According to reports, his 15-year-old sister, Lottie, had been receiving creepy Twitter and text messages from a 24-year-old man. This Internet creep received a phone call from the pop star, but it was Louis playing the part of concerned older brother!

We're not talking about weird tweets or messages that were borderline flirty, this dude was so creepy, he was sending the teen half-naked photos of himself!

"What do you think of this picture? I am a model," this person told Lottie. "You should be a model."

At this, Louis' sister responded: "I'm 15."

Eventually, Lottie decided to get off of Twitter. Once the text messages came in as well, she turned to her busy brother for help.

Without hesitation, Louis called the creep up.

"Louis wanted to be focused on playing at one of the biggest venues in the country but his sister comes first and he wanted to make sure he was protecting her," an insider said. "He didn't hold back when he called the bloke. He was really angry about what had been going on."

Louis to the rescue!

"You're 24 and she is 15," Louis told the creep on the phone, according to The Daily Star. "What are you thinking? Don't even think about coming to [Manchester's Etihad Stadium] tonight. I don't want to see you there."

Do you think Louis performed his brotherly duties well in this situation?
