The singer turned 28 on Tuesday, and she and her 51-year-old beau of five years marked the occasion in sunny Jamaica. The pair spent a romantic getaway on the island, and documented their time on Instagram. Knowles has since deleted the pictures, including one of herself and Ferguson smiling and embracing in the water, but wrote, "Today couldn't have been more perfect. I couldn't have smiled harder. Thank you for all of your lovely and wonderful wishes. They warmed my heart and I simply feel grateful of all the love."
The intimate photos have fueled rumors that the couple are now engaged. According to website MediaTakeOut, Ferguson proposed on Monday ahead of Knowles' birthday. The singer was previously married to Daniel Smith, but the couple divorced in 2007. She and Smith have one child from their marriage, son Daniel Julez.
