Nearly a year after reuniting and rekindling their relationship, Pink and her husband, motocross star Carey Hart, really want to expand their family. “Their marriage is stronger than ever, and they are ready to take the next step,” a friend of the couple’s tells In Touch exclusively. The 30-year-old singer and Carey, 34, are so serious about starting a family that they’ve set aside time to get down to the business of making a baby. “They are going on a romantic vacation around Christmas,” the pal adds. “They can’t wait to be parents!” Pink and Carey announced their split in 2008, after two years of marriage, then got back together.
