Celine Dion is the latest celebrity having a baby later in life. While for some it’s because of career demands, in Celine’s case, it’s been because of health issues. She, now 42, and husband Rene Angelil just announced that they’re having twins, but it hasn’t been without great difficulty that she’s pregnant.

She’s had numerous attempts using in-vitro fertilization (IVF), which for her involves flying from Florida (where she lives) to New York. She’s also had acupuncture treatments in Montreal, Canada (she and Rene are originally from the province of Quebec). She told People, “I feel like I’ve been pregnant more than a year,” because of the IVF efforts, and that this pregnancy has been physically and emotionally exhausting. She went through six years of IVF treatments just to get pregnant with son Rene-Charles, now nine, and it’s possible that the twins are from embryos previously frozen.

Celine, who had a huge show at Caesar’s Palace in Vegas that lasted five years and ended late 2007, is planning to rest because of the priority she’s putting on the babies, though she does have another Vegas show starting in 2011. She was named Calendar’s number one artist of the decade primarily because of the sales figures she pulled in thanks to the Caesar’s engagement.
