The thrilled 40-year-old singer announced the happy pregnancy news via Twitter, on Monday, April 28.
“Ayda and I are delighted to announce that Theodora Rose Williams is going to be a big sister. RW xxx,” he wrote.
Williams has tattooed, earlier this year, a teddy on his arms in honor of his daughter, whose nickname is Teddy.
Last October, Williams opened up in an interview with BBC Radio 4 about fatherhood.
“She’s difficult to talk about,” he said about his daughter. “Everything I do is for her.”
“Every time I open my mouth now in the studio it’s a song about her, it would bore people to death but I could do a trilogy of albums about her.”
“There is a reason for me to everything now. I wasn’t to going to have a kid and I wasn’t going to get married. Then I met someone who was amazing and I fell in love with her completely and I changed all my thoughts and feelings about that,” he added.
The couple, who welcomed their first baby Theodora Rose in 2012, got married in August 2010 on his Beverly Hills mansion.
