Congratulations may be in order for One Direction singer Louis Tomlinson with reports rife that he has become a father. Speculation is mounting that the boy band star's ex-girlfriend Briana Jungwirth has given birth to a baby boy although the news is yet to be confirmed.

According to a One Direction Twitter fan account, the news was announced by Jungwirth's grandmother Marianna Case, who is said to have shared an Instagram post. Case appears to address Tomlinson, 24, directly, writing: "Louis just let Ur heart dance. U now have another you. A gift that will want to be just like YOU. Love him & my young grandchild that gave him to you. LET her know she's special.

"She just wanted to love U not even knowing who U were or your profile Ur & reputation. Be free & just LIVE. It's simple. Not complex. Be free with love of yourself & Ur child that will want to be just like U. That is, If U let him. He'll be watching all U do. And hope to be just like U, if U let him. A little boy that's just sees you. Take charge.& repect Briana that was willing to go throw it all. She's never loved before."

Neither Tomlinson or Jungwirth, 23, have confirmed the reports although it is believed her due date was some time in January 2016. The Los Angeles-based stylist hinted that the baby was on its way when she posted a photo of her bump on Instagram with the caption: "So ready for you my love!" After weeks of rumours, Tomlinson confirmed in August 2015 that he was set to become a father for the first time, saying during an interview on Good Morning America: "Obviously it's a really exciting time, so I'm buzzing, thank you."

It is believed Tomlinson and Jungwirth enjoyed a brief romance following his split from long-time girlfriend Eleanor Calder. The pair were first spotted partying together at a Hollywood nightclub in May 2015 and the pregnancy rumours surfaced two months later in July. Although they are no longer an item, Tomlinson and Jungwirth are expected to co-parent the child.
