Season of Love

From candlelit dinners to splashy vacations, the summer is turning out to be full of romance for these hot Hollywood couples!

Kylie & Timothée

UNLIKELY PAIRING

Timothée Chalamet didn't expect it to last this long, a source admits, and Kylie Jenner's always been more into rappers. (Her exes include Travis Scott, 32, and Tyga, 33.) But nearly six months after the Oscar-nominated actor, 27, met the mom of two, 25, at a Paris fashion party in January, says the source, their "hot chemistry" remains palpable: "They're really into each other." They've tried to keep their romance private by spending date nights at his Beverly Hills home, but they've also "snuck back to Paris together," adds the source, who says "the secrecy is a big turn-on." There's one hurdle, however. "His parents are apprehensive about him dating a reality star," says the source. "But Kylie plans to win them over this summer."
