For Cristina, 27, the knowledge that she would have a hard time conceiving a child did not hold back her dream of becoming a mom, and she credits someone in particular for helping her through - Céline Dion. "Through the whole infertility process I kept thinking about Céline and how she didn't give up," Cristina recalls. "She went through several attempts to become pregnant and she was successful; that's why I didn't give up". Now pregnant with triplets, Cristina gets the chance to thank her inspiration in person when Céline surprises her in Rachael's studio - and Rachael follows it up with a huge surprise of her own for the expectant mom!
