Tori Spelling's last pregnancy nearly killed her.

The blonde actress has revealed she nearly lost her life when she was carrying newborn son Finn because she was diagnosed with placenta previa - a condition where the placenta covers the cervix and causes internal bleeding - at 20 weeks.

Tori - who is married to Dean McDermott - was rushed into hospital, where she spent 10 weeks receiving treatment followed by four months of bed rest, and she was even close to having her pregnancy terminated to save her life.

However, she battled through and gave birth to Finn Davey McDermott on August 30 and the '90210' star admits the bond between her and her baby is so strong because of the ordeal.

She said: ''When they put him in my arms I was like, 'We made it.' We have an insane bond. We've been through hell and back.''

The 39-year-old actress admits the biggest fear she had when she was told she could die was leaving her three other kids, Liam, five, Stella, four, and 12-month-old Hattie, without a mother.

She added to the new issue of Us Weekly magazine: ''I just remember thinking, 'I can't leave three children behind.' ''
