Tina, 61, tied the knot with the 68-year-old actor earlier this month and she said that the idea came in September last year, reported People magazine.
"In September we went on a boat with Beyonce and Jay-Z and when we came out one night dressed to go to dinner, Blue said, 'Oh, you all look beautiful. When are you all getting married?'" Tina recalled.
"Richard said, 'Oh, Blue, soon. Do you approve?'"
Tina and Richard tied the knot on Sunday, April 12 on a super yacht cruising around Newport Beach, California. On the boat that holds 300 capacity, Beyonce and his husband Jay-Z were seen onboard.
