A thrilled Britney Spears has said "I do" to beau David Lucado's marriage proposal -- and now she's planning a secret wedding in Hawaii, say sources. "Britney is head over heels in love again and wants to marry soon after the new year," revealed a family insider.

"Britney is ready to marry again and have more children," revealed the source. "She's dying to have a little girl and she's certain she's found the right man this time. This is the first time she's let a man actually propose to her. In her other two marriages, she proposed to them. "Now she's busy making elaborate plans for a Hawaiian wedding and favors Maui, where she's had many wonderful times." (Print Edition - 12/16)
