Singer Pink has been mum on pregnancy rumors

When pregnancy rumors about her first floated in April, pop star Pink deflated them with a humorous Twitter post. This time, however, she has so far kept mum after Us magazine reported Wednesday that the "So What" singer is pregnant with her first child.

"She's 12 weeks along," a source told the magazine. "She wanted to do it between tours, when she has some time off."

Pink, whose real name is Alecia Moore, 31, and her husband, motocross racer Carey Hart, 35, were married in January 2006 after four years of dating, but separated in February 2008.

By the following year, however, the two were in marriage counseling, and this past February, Pink told Oprah Winfrey the couple were back together.

"Pink was determined to make the relationship solid," said the source. "Now she's really happy, and she's excited she got pregnant so fast! She'll be a brilliant mother."
