Cat Deeley shows off her baby bump in a new bikini photo.

The pregnant 41-year-old "So You Think You Can Dance" host took to the beach Sunday ahead of the birth of her second child with her husband, comedian Patrick Kielty.

Deeley shared a photo on Instagram of herself soaking up rays in Malibu, Calif. The expectant mom shows a smile in a yellow bikini with a floral print.

"#sundayfunday," she wrote, adding several fish emojis.

Deeley and Kielty married in September 2012, and already have 2-year-old son Milo. Deeley posted a cute video Friday of Milo wading in the water with their family dog.

"One boy, his faithful hound and rock pools #fridayfeeling," she captioned the clip.

Deeley announced her pregnancy in January, saying she is "so excited" to welcome another baby in the spring. She discussed her role as mom in an interview with People the same month.

"I think it's a hard job -- if you want to do a really good job, it's hard work. If you really care and you really want to make it, you put pressure on yourself," the star said.

"But it's the best job in the world," she qualified.

"And it's thrilling and funny and cracks [you] up and makes you have this, the most immense feeling of love that you're ever had in your life."
