UPDATE: PEOPLE magazine have confirmed the birth. According to the site, "Louis Tomlinson and Briana Jungwirth welcomed their first child, a son, on Thursday, Jan. 21 in Los Angeles, a source close to Jungwirth confirms to PEOPLE exclusively."
In news that will probably dominate today's headlines, a bunch of sources are claiming that One Direction's Louis Tomlinson is officially a father after Briana Jungwirth has allegedly given birth to a baby boy.
Speculation that Briana had been admitted to hospital began to surface after a screenshot of an Instagram post allegedly belonging to her grandmother Marianna Case began to spread around online, apparently confirming the birth of Louis and Bri's son.
The post in question reads: "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 (sic).'
This video, allegedly posted on Marianna's Instagram, also fuelled rumours that the baby had been born, although it's not been confirmed that the account officially belongs to her:
Oh, and there's also the fact that this recent insta pic of Briana confirms that she's been looking ready to pop for a while now:
Although nothing has been confirmed yet, sources did confirm to The Sun that Louis is currently with Briana in a Los Angeles hospital, which obviously led to a pretty wild reaction on Twitter.
