Tori Spelling is repairing her relationship with her estranged mother - through their mutual love of the star's young son LIAM. The former Beverly Hills 90210 star has enjoyed a strained relationship with mum Candy - which she blames on the attention her father Aaron heaped on her after her birth. She says, "My mother was his world. Then I was born and then I was his world. That's a hard thing for a mother to adjust to." But things are gradually improving, with the help of 11-month-old Liam. She explains, "She (Candy) is developing a relationship with Liam, and that's the most important thing to me. "It has bonded us in a way that can't be broken. I understand her better because I am a mom as well." Spelling is currently expecting her second child with husband Dean MCDermott.
