One Direction's Harry Styles is now out of the singles' loop. Sorry ladies. 

It appears that Styles has completely moved on from the string of girls romantically linked to his name and is now dating Victoria's Secret model Nadine Leopold, Us Weekly has learned.

To start the year right, the 20-year-old British boy band member has found himself a new inspiration in the person of Leopold.

"Harry has been getting more serious with Nadine," an insider said of Styles and Leopold's romance.

Styles reportedly got introduced to the Austrian model by CAA agent Jeff Azoff back in November, and since then the two have been seeing each other.

Sources say the they are not dating exclusively yet, but they sure do love "spending lots of time together," reports Daily Mail.

For her Leopold's 21st birthday on Tuesday, Jan. 6, Styles showed off his romantic side by preparing something special for the lady who currently holds his heart.

"He planned a few activities for her birthday," said an insider, adding that the twosome enjoyed sumptuous dinner at Craig's in West Hollywood on her birthday and continued the celebration by dining at Rande Gerber's Malibu eatery Cafe Habana on Wednesday.

"Harry is having a good time being a young rock star," a source dished. "You will know he has a girlfriend when he steps out on the red carpet with one. Until then, he's having fun and enjoying life."

Before going out with Nadine, Harry was rumored to have quickly dated Kendall Jenner. He was also linked to Cara Delevingne and was confirmed to have an ended-too-soon relationship with "Blank Space" hit maker, Taylor Swift. 

Meanwhile, on Thursday, Styles spent some time with his friends at the Westside JCC in L.A. playing indoor hockey.

Per TMZ's sources, the British singer, who is known for being a ladies' man, played impressively, scoring several goals during their gaming session.
