Briana Jungwirth's baby bump is steadily growing as the makeup artist was snapped while bonding with Louis Tomlinson's family in Los Angeles recently.

Apparently, the One Direction member's parents arrived in the US to watch the band perform in Los Angeles and were seen shopping with Briana Jungwirth who was displaying her baby bump in all its glory.

"Briana is said to be due at the end of January or early February, so perhaps they were all shopping for baby goods. The last time Briana revealed her baby bump was while grabbing lunch in her hometown of Calabasas, California, on October 31," said Hollywood Life.

Previously, Daily Mail reported that the parents of Louis Tomlinson and Briana Jungwirth have already agreed to the custody rights for the baby.

"They're adamant it won't get messy. Briana's parents have made it clear they aren't interested in money - they just want what's best for the baby," a source told the tabloid.

Also, Louis Tomlinson's mom, Johannah, has been helping Briana Jungwirth deal with morning sickness and loss of appetite because she's a certified midwife.

The source added, "Johannah is bursting with pride of having her first grandchild and doesn't want to miss a single moment. Which will be quite difficult given the trans-Atlantic distance between where the two families live."

When news of Briana Jungwirth's baby bump came out, Louis Tomlinson immediately rented a five-star hotel where she can stay for a while. Later, she rented out an apartment in Los Angeles where she and her family are staying now.

Amid all the news, Simmon Cowell, who is behind the success of One Direction, is also helping out.

"Simon loves being a dad and is more than happy to get involved. His plan is to help move the Jungwirth family to the exclusive 'The Oaks' neighborhood near their current home in Calabasas," said Daily Mail. "It was his preference to have them in a gated home near world-renowned hospital Cedars-Sinai but Briana's parents politely declined."
