Los-Angeles-based stylist Briana Jungwirth reportedly wants One Direction star Louis Tomlinson to propose to her.

According to Life & Style, Jungwirth who is set to welcome a baby with Tomlinson, wants to get married before their child arrives early in 2015.

"Briana told Louis that she wants a ring on her finger before the birth of their child," a source said.

"She's piling on the pressure for him to make a commitment. She knows it's unromantic and perhaps too rushed, but Briana feels like she needs to give Louis an ultimatum because he's so laid-back," the insider added.

"Briana came from a broken home and she doesn't want their child to share the same fate," the source said.

Tomlinson met Jungwirth earlier this year through mutual friends, after he split up with Eleanor Calder in March. The two were also spotted on a number of dates back in May in Hollywood.

It was previously reported that Calder was shocked when she heard the baby news.

Meanwhile, Tomlinson addressed the baby rumours during One Direction's appearance on Good Morning America on 4 August.

Show host Michael Strahan asked: "Louis, from one father to another, I want to congratulate you on your upcoming fatherhood. So, how are you feeling?"

Tomlinson replied: "Obviously it's a really exciting time, so I'm buzzing, thank you."
