Joe Jonas and Gigi Hadid were not shy about public displays of affection during their outings in Paris over the weekend.

The reality television personality turned model and her singer boyfriend lounged on the grass of Parc Monceau in the romantic city on Friday. Hadid, 20, reclined with her head in Jonas' lap, as they talked with Stella Maxwell, a model and friend of Hadid.

The 26-year-old former Jonas Brothers front man also stole a passionate kiss from the blond beauty. The couple did not appear to care who saw them cuddling and kissing in the park.

The "Just In Love" singer accompanied Hadid to the French capital for Paris Fashion Week, where she was working as a runway model.

Hello Fashion reports that Jonas had a front row seat at the Balmain show on Thursday, as Hadid prowled the catwalk showing off Olivier Rousteing's Spring/Summer 2016 collection alongside models Alessandra Ambrosio, Kendall Jenner, Doutzen Kroes and Joan Small.

Hadid looked stunning as she modeled a Balmain wraparound brown top and embellished leather pencil skirt, with her long hair tied back into a sleek ponytail.

When the show ended, Jonas hurried backstage to congratulate his girlfriend on a job well done. The couple were later spotted leaving the venue together.

In Paris from Thursday to Sunday, Hadid walked the runway for Balmain, the Elie Saab spring 2016 runway show and Giambattista Valli. She also attended Vogue Magazine's 95th anniversary party on Saturday night with Jonas by her side, reports The New York Times.

On Sunday, the couple were seen leaving the Hôtel Costes in Paris and stopping for a romantic lunch at Café de Flore, reports the Daily Mail.

The couple enjoyed exploring the French city on Hadid's time off from modeling. They went shopping, sight-seeing, enjoyed French cuisine at trendy restaurants and rode a Parc Monceau carousel with Hadid's best friend Jenner, according to Entertainment Tonight.

Hadid and Jonas have been dating since May.
