The 31-year-old singer - who is married to motocross racer Carey Hart - is 12 weeks pregnant, and is "really happy" with the news. A source said: "She`s 12 weeks along. She wanted to do it between tours, when she has some time off." The pop star - real name Alecia Beth Moore - broke up with Carey in 2008 but the pair reconciled in 2009, and the couple are believed to be stronger than ever. The source added: "Pink was determined to make the relationship solid. Now she`s really happy, and she`s excited she got pregnant so fast! She`ll be a brilliant mother." In recent days the singer has posted a number of posts on twitter hinting at a change to her usual pop star lifestyle. She wrote: "I got so much done today. i feel completely capable of domesticity. how long will this last til` i`m climbing the walls? we shall see. (sic)" She also said: "Thinkin about hibernating for winter. (sic)" Pink has previously revealed she would love to have a child, saying earlier this year she couldn`t wait to have a baby. She said: "At this point, we`re still trying not to, but I can`t wait to not try not to."
