Eleanor Calder, who dated Louis Tomlinson for four years, was shocked upon hearing that he's got somebody pregnant just four months after their split.

The news about Louis Tomlinson having a baby with Briana Jungwirth, said to be a stylist who's been his friend for a long time, hit the tabloids in the past couple of days. Apparently, Eleanor Calder heard the news from the One Direction member's own mother.

The source told Hollywood Life that Eleanor Calder got "kind of sick to her stomach."

"It's not like they had been broken up for long! Louis mom broke the news to her - they're still very close. This is not the kind of news any ex-girlfriend wants to hear, especially when you dated someone for so long and then the next person who comes along ends up getting pregnant," the source added.

Even if Louis Tomlinson was ecstatic upon hearing the baby news from Briana Jungwirth, and vowed to support her, he's not about to get married.

"He's really enjoying the single life right now and has no plans on settling down anytime soon," the source added.

"Unfortunately, the other girls he had been 'dating' are really jealous and upset about the baby news. All of them were hoping to be the one to finally land Louis."

But who is Briana Jungwirth?

She's a stylist based in Los Angeles, California. She was snapped with Louis Tomlinson once before in May this year, after the One Direction hottie's breakup from Eleanor Calder.

"The British boy band member and Jungwirth, both 23, met through mutual friends earlier this year after his split from longterm girlfriend Eleanor Calder in March and were spotted on a number of dates in May," said People.

The insider added, "Briana is a really lovely girl; she's absolutely not interested in Louis' fame. She's very private and most of the time they spend together is out of the public eye, just hanging out with their friends."
