The twosome, who are now close friends, had a brief dalliance in May this year, around two months after he ended his long-term relationship with girlfriend Eleanor Calder. 

The boyband star was seen on a string of late night dates with several different women after his break-up from his long-term love, hitting the clubs in Los Angeles and London, and it's around this time that he enjoyed a fling with Briana. 

It has been reported that the 1D pop star, who rose to fame with the successful boy band back in 2010 on The X Factor, is intending to support Briana every step of the way throughout pregnancy and motherhood. 

The young twosome are no longer in a relationship, but they remain close friends.

The sighting of the expectant mum comes as X Factor boss Simon Cowell has shared his thoughts about Louis' impending fatherhood.

In a new interview with The Sun on Sunday, the TV and music mogul explained that he offered the young singer practical advice.

Simon revealed he told Louis to 'man up' and embrace the positives of having a child, adding, 'You're fortunate because you're in a position to be able to look after the baby and not worry about too much else'.

The talent show guru is adamant the unplanned pregnancy won't tarnish the boy band's family-friendly image, joking to the paper's Dan Wootton, 'He didn't kill anyone, he just got someone pregnant.'

The 55-year-old star also confirmed the boys are planning to take some well-deserved time off next year to enjoy themselves. 

Recent reports claim that Louis is set to pay £20,000 per month in child support and maintenance bills once the baby is born next year.

In total, it's thought he could be set back as much as £10million in total. 

The heartthrob is also reportedly planning on buying a gated home for the new mother and their baby once it is born.

WHO IS BRIANA JUNGWIRTH? MEET THE WOMAN BEHIND THE HEADLINES: 

The 23-year-old is a Los Angeles-based stylist who works in the fashion industry,

She was introduced to Louis by a mutual friend earlier this year, with the pair pictured on a string of nights out together in May.

The pretty blonde is thought to live in Calabasas, California, the same exclusive neighbourhood where the Kardashians reside.

Louis is reportedly house-hunting in the area to be close to her.

Described as 'a very private person', Briana is not thought to have any social media accounts and doesn't even appear to have a Facebook page. 

Sources claim she only attended her first One Direction concert recently and is not interested in his fame.

She is not in a relationship with Louis, with a mutual pal describing the two as simply 'close friends'.

Briana is also said to get on very well with Louis' parents, and she spent the July 4th weekend hanging out with his mother Johannah and stepfather Dan after they flew to the US meet up.

A source earlier told The Daily Mirror: 'This is a case of a very short-term thing that will end up costing Louis around £10million. But he knows this is his responsibility.' 

A representative for Louis Tomlinson refused to comment.

Earlier this week, Briana's father revealed to MailOnline that she had become overwhelmed since being thrust in to the limelight.

'The publicity and everything, it can be overwhelming yes,' Joe Jungwirth said from his home in South Dakota. 

'Briana's really shy, she's strong but shy, she's tough but shy and she's having a tough time with it, it's stressing her out right now, she's texting me all the time.' 

Briana's ex-boyfriend has also come out of the woodwork, telling The Sun that he was surprised upon hearing the news.

Maxx Fieldman, a 22-year-old student, said: 'Louis could do a lot worse than give it a go with Briana because she's a great girl. She's an attractive girl. Louis is a lucky guy.'

He added: 'It's definitely a shock. I would never have imagined she would end up having a baby with a pop star.'
