Summer love is heating up among the celebrity crowd with brand-new pairings as well as reignition on old flames. While some couples are openly displaying PDAs complete with coded tattoos referencing their new loves, others are opting for lengthy discretion before finally stepping out in public. Here are just a few of the sizzling romances that are putting love on the season’s front burner.

Josh Duhamel & Eiza Gonzalez

Josh Duhamel and Eiza Gonzalez, who have been quietly dating for months, recently made it public by going to Matsuhisa in Beverly Hills for sushi. The 45-year-old actor split from Fergie last year after eight years of marriage, while the Baby Driver star was previously linked to Liam Hemsworth. They were also spotted having dinner in Sherman Oaks. “They are having a fun weekend,” says a source. “Their relationship started out slowly, but lately, they are spending more time together. They seem very happy.”

Chris Pratt & Katherine Schwarzenegger

Guess who acted as matchmaker for the Jurassic World actor and daughter of Arnold Schwarzenegger and Maria Shriver? “Maria helped set them up,” a source said. “It’s still new.” The pair have been out on multiple dates and were spotted together on Father’s Day.

Justin Bieber & Hailey Baldwin

Recent photos of these two old flames hint they may be back together, despite one insider suggesting they’re just friends. “They are two single people that enjoy each other’s company,” said the source. Bieber and Baldwin dated in 2016 and broke up, but they were seen around N.Y.C. several times in June. AND they were photographed holding hands.

Ariana Grande & Pete Davidson

They started dating in May after he split from Cazzie David and she broke up with Mac Miller. Their engagement made news just weeks later in early June. Since then they’ve been seen in some notable PDAs.  Word that he got two tattoos appearing to reference the singer came just days after the Saturday Night Live star made things official with Grande on Instagram. They show up at one another’s concerts and stand-up shows, and they leave cute comments on each other’s Instagrams.

Kendall Jenner & Anwar Hadid

This one may already be over and done. Kendall was seen smooching Anwar just days after she was linked to Philadelphia 76ers star Ben Simmons. However, by mid-June she was back to Simmons again and Anwar was seen making out with a French model.

A source explained it all. “Kendall is having fun. She doesn’t want a serious relationship and is just enjoying being single. She feels that whenever she has been serious about guys in the past, it’s kind of a mess and doesn’t work out.” The P.S. on Anwar is that he’s the brother of Bella and Gig Hadid.

Jennifer Lawrence & Cooke Maroney

One of Lawrence’s close friends introduced her to Maroney, who works in the New York City art scene. Since then they’ve been spotted showing PDA several times around NYC. Lawrence split from her mother! director Darren Aronofsky last November.
