Tomlinson and Jungwirth were reportedly an item for a brief time last May after he split from his longtime girlfriend, Eleanor Calder, in March. He's currently rumored to be romantically involved with The Originals star Danielle Campbell after they were spotted out and about in Chicago over the holidays.

"Louis is happy and very excited about becoming a dad and he thinks Briana will be an amazing mother," a mutual friend of the new parents told ET back in July. "It was a surprise at first, but he and Briana are very, very close friends and this has brought them even closer."
