Following his two-week romance with Briana Jungwirth, the 1D star could be facing a maintenance bill of £20,000 a month until his child is 18, The Mirror reports.

The 23-year-old singer is also said to be budgeting several million pounds to move Briana and the baby into a gated home in Los Angeles.

A source revealed Louis is excited about the baby, saying, "He can't wait to become a dad.

"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."

Louis and Briana, also 23, got together in May this year after he split from long-term girlfriend Eleanor Calder. Wasting no time, he is reportedly already house-hunting in the LA suburbs, where a home for Briana and the baby - due in early February - is likely to cost around £4million, adding significantly to his already hefty maintenance bill.

With millions of young fans around the world, father-to-be Louis will be looking to set a good example and do things right. "Louis is the first member of One Direction to have a baby. He's pulling out all the stops," the source added.

On Friday (17 July), Briana stepped out publicly for the first time since the news of her pregnancy broke, as she was snapped running errands in LA, according to People.

A friend of Briana's said, "Money has always been a bit tight [for her], so this really will change her life."
