… And now it's official. One Direction singer Louis Tomlinson took to Instagram to officially declare that he is off the market.

His lady love, though, isn't the mother of his recently-born child, it's actress Danielle Campbell, who he has been linked to for several months.

On Monday, Louis shared a black and white image of himself kissing the "Originals" star on the cheek, captioning it simply, "Lucky."

The social media conformation (and really, does it get anymore official than that!) confirms romance speculation that has been mounting for months. The two first sparked romance rumors back in December.

Since then, they have been photographed on several dates, and in February they were spotted holding hands while celebrating her birthday in Los Angeles.

To say the romance has been tested already may be an understatement. In January, while Louis and Danielle were still flirting and perhaps even formally dating, he welcomed his first child, baby boy Freddie, with L.A.-based stylist and friend Briana Jungwirth.

"He is healthy and pretty amazing," he tweeted after Freddie's was born. "I'm very happy!!"

Since One Direction's break or break up, depending on who you believe, Louis has been ever the doting dad, as he's been photographed several times with his son. Several reports indicate that all the members of 1D are focusing on beginning solo careers.

Unlike his fellow band members, Louis has embraced his fatherly duty. But, he shares custody with Briana.

In February, the two reached a temporary custody agreement that allows Louis to reportedly have access to Freddie for a few hours at a time during the week. Overnight stays were prohibited in the agreement.

As with many celebrities in similar situations, Louis feared that she was after his money, so he armed himself with lawyers before the agreement was struck.

Briana's cousin, though, said she's far from a gold digger.

Speaking to Now magazine, Ashley Jessica countered claims that her cousin "trapped" the singer. She claimed that neither she nor Briana knew who he was when they first met him in a nightclub last year.

As for his relationship with Danielle, Ashley says that's "just bad timing," considering he and Briana still have a newborn.
