Singer Carnie Wilson is expecting her second child with her musician husband Rob Bonfiglio.
The Wilson-Phillips star, 40, is already mother to daughter Lola, who was born in 2005.
She tells OK! magazine, "My due date is June 24 (09). I'm having a C-section probably June 10."
And Wilson, daughter of Beach Boy rocker Brian Wilson, admits she hopes to join the legion of celebrity mums who've given birth to a double bundle of joy.
She adds: "I went (to the doctor) for blood tests, and my hormone levels were climbing. My levels were over tripling so my doctor said to me, 'You might have twins in there.'
"I can't stop thinking about twins! My sister had twins; my grandmother was a twin and my grandmother's aunt had twins. I had my first ultrasound and we only saw one sac, but it's not confirmed that it's not two because one could be hiding in the back of the other... we'll see."
Wilson and Bonfiglio married in 2000.
