(showbizspy.com) - Justin Timberlake is reportedly set to propose to girlfriend Jessica Biel.
The singer, who has previously dated Britney Spears and Cameron Diaz, has already started looking at potential wedding venues; and Jessica has not been drinking recently, sparking pregnancy rumors.
A source said, "Justin is 27 and thinking about marriage and kids.
"For the first time in his life he is feeling settled and has definitely decided to pop the question to Jessica.
"He is so happy with her. They spent quite a bit of time apart recently when Justin was working with Madonna. That made him certain Jessica was the person he wanted to spend the rest of his life with."
The 'Sexy Back' singer is said to have his eye on the West Indian island of Mustique as a venue for the wedding. It's described as "an exclusive, 1,400-acre island in the southern Caribbean with lush, rolling terrain cooled by trade winds, surrounded by pristine white beaches and clear, aquamarine waters," according to the island's official website.
Justin wants the complete privacy for the couple's big day - and because the island is privately owned by those who live there, he would be able to ban all paparazzi.
His friend added, "Although Justin has lived his whole life in the public eye, he feels his wedding is the one day that should remain private.
"To get all his close friends and family to Mustique will cost a fortune. But he can't put a price on how he feels about Jessica.
"Then there are the rumours about a baby being on the way."
