Things are heating up between Lindsay Lohan and Calum Best – literally.

The actress and the British TV personality spent a romantic weekend in the Bahamas, where they celebrated the opening of the Cove Atlantis on Paradise Island with parties, sunbathing and lots of PDA.

The couple, who also got affectionate at a party in New York City a few days earlier, arrived in the Bahamas on Friday evening in time to catch a poolside Janet Jackson concert alongside John Travolta, Rob Lowe, Whitney Houston, Spike Lee, Michael Jordan and Tyra Banks.

Sitting with friends in the VIP area, Lohan and Best danced to Jackson’s 20-minute set of greatest hits and wrapped their arms around each other to watch a fireworks show over the Caribbean resort’s white-sand beach.

After the concert, the pair moved on to the after-party at the Aura nightclub, where they shared several kisses in a VIP booth. While most of the partygoers left Lohan, 20, and Best, 26, alone, music legend Quincy Jones stopped by the table for a chat.

“[Lindsay is] a good girl,” Jones told PEOPLE the next day. “She’s very young, but she has a good head on her shoulders.”

On Saturday, the couple spent several hours in a private cabana on Cove Beach. As the temperatures soared, Best rubbed sunblock on Lohan’s shoulders before they headed into the water for swimming, splashing and still more kissing.

That evening, they returned to Aura, where they sat in the same booth as they had the night before. “They seem to have had a wonderful weekend,” says an onlooker. “They’re enjoying their time in paradise.”
