AceShowbiz - Supermodel Gisele Bundchen's world turned "upside down" when she learned her new boyfriend's ex was pregnant.
"Two months into our relationship, Tom told me that his ex-girlfriend was pregnant," Gisele writes in her memoir "Lessons: My Path to a Meaningful Life". "The very next day the news was everywhere, and I felt my world had been turned upside down."
Gisele admits the situation was not ideal and it took her a while to adjust, but she's glad she stuck it out and became an instant stepmom.
"It wasn't the ideal situation for anyone; there's no manual to prepare you for that," she tells People magazine. "But I'm so grateful for her (Bridget). I know this was hard, but I couldn't imagine my life without him (son Jack). I call him my bonus child."
The 38-year-old's relationship with Jack also made her "want to start a family" with Tom sooner than they had planned.
"He opened my heart in ways I didn't even know my heart could expand," she writes. "I fell in love with him. We wanted Jack to have a brother or sister close in age."
But motherhood was tough on Gisele at first.
"I kind of lost myself. It was like a part of me died," she revealed last month. "I'd been this very independent person. It was all about me. But now I had this little being, and I suddenly felt I couldn't do other things and that was very hard for me. All I ever wanted was to be a mom, but when you're actually experiencing that, it's a shock."
