WASHINGTON (CNN) -- When not attending to her official duties, first lady Laura Bush enjoys working out, listening to music and watching sports on television, she told cooking guru Rachael Ray in an interview that was released Monday.

When it comes to Valentine's Day, the first lady confided to Ray that President Bush is "not very good" at remembering the date.

"There's a White House florist so they always send up flowers and he signs the card," the first lady said.

While there are "no special" Valentine's Day plan, the first lady said she is looking forward to "a really romantic dinner" with her husband.

The first lady also told Ray that she hits the gym three days a week with her sister in law and legendary crooners Luther Vandross and B.B. King can be heard playing "very loud" in the background.

"We lift weights and I get on the treadmill, on the elliptical," Bush said.

When it comes to the first lady's beauty tips, Mrs. Bush suggests simply, "get a lot of sleep --I think a lot of sleep is healthy."

Her two twin daughters, Jenna and Laura, aren't "picky eaters," though neither "eat a lot of meat," Bush said.

"They mainly have fish and vegetables...and beans, they love beans,"she said.

Asked what book she is currently reading, the former librarian said she just finished "Glass Castle" by Jeanette Walls, a "very good and interesting memoir" that former first lady Barbara Bush recommended.

"It's very nice to [exchange books] with your mother-in-law," the first lady said.
