AceShowbiz - Love is in the air for Olivia Rodrigo and Louis Partridge. The "Driver's License" hitmaker and her actor boyfriend were photographed packing on PDA while attending the 81st Annual Venice Film Festival over the weekend.

In photos circulating online, the "Vampire" singer could be seen giving a bright smile to the "Enola Holmes" star as she showed support for his series "Disclaimer" premiere at the event. While gracing the red carpet, Louis, meanwhile, leaned in to give the 21-year-old beauty a sweet kiss on the cheek.

For the occasion, Olivia was a vision in a chic black dress with a plunging neckline as well as matching clutch and strappy heels. The award had her black hair styled in an updo as she put on red lipsticks to complete her look.

As for Louis, the 21-year-old English heartthrob donned a white buttoned shirt and gray pants for the Saturday, August 31 event. On "Disclaimer", the actor stars opposite Cate Blanchett.

The couple's red carpet came after they made their romance Instagram official. Louis made use of his account to share a black-and-white photo of them together. In the snap, the lovebirds were walking hand-in-hand through a hotel lobby while gazing adoringly at each other.

The pair recently made their first red carpet appearance as a couple at the Venice Film Festival. Olivia embraced her signature '90s-inspired style with a vampy black slip adorned with velvet floral embellishments and a flower detail on the neckline. She completed her look with strappy black heels, Fiametta earrings, Lowercase NYC sunglasses and a touch of burgundy lipstick.

Louis, on the other hand, looked dashing in a classic black suit, white shirt, platform boots and sunglasses. His slicked-back hair and popped collar added an effortless cool to his ensemble.

Olivia and Louis were first romantically linked last October following a number of "dinners and nights out" in London together. Prior to dating Louis, the "traitor" singer was in a relationship with Zack Bia.
