Briana Jungwirth SPOTTED: She’s in London to cheer Louis on

After spending a reclusive few months in Los Angeles, Briana Jungwirth is spreading her wings.

The 23-year-old, who is expecting a baby with One Direction's Louis Tomlinson in early 2016, was spotted by eagle eyed fans in London last night.

California native Briana was up front at One Direction's O2 gig, the first of six at the massive music venue. Although she was well hidden in the VIP area, keen concert-goers still managed to take a few sneaky photos:

The stylist, who had a brief fling with Louis back in May, hid from the media for weeks after the pregnancy announcement, staying in an LA hotel paid for by Louis's management team.

However she was spotted out and about with her mum a couple of months back in her hometown of Oxnard, California. The pair hit their local civic offices to collect a passport application form – perhaps for Briana's trip to London?

Despite Briana's front row presence at the 1D gig, she and Louis seem to be just good friends for now, having grown closer since May's news.

And while he has been staying quiet about the pregnancy so far, Louis did admit in a recent interview that he was "excited" and "buzzing" to become a dad
