Tori Spelling's mother has urged her to try to save her marriage.

The former 'Beverly Hills 90210' star was ''absolutely blindsided'' when her husband Dean McDermott, 47, checked into a rehab facility last month to address some personal issues, after he was accused of having affairs with multiple women, but Candy Spelling thinks the 40-year-old actress should stand by him for the sake of their four children, Liam, six, Stella, five, Hattie, two, and 15-month-old Finn.

A source told gossip website RadarOnline.com: ''Candy certainly is not a big fan of Dean at the moment, because of the hell he has put her daughter through. But she does recognise that he is a great father and he does love Tori. Tori finally confided with her mom, about her ultimate fear that Dean could cheat on her again in the future. It was a very open and honest conversation. At the end of it, Candy told her daughter, 'You will never know unless you try.'

''Since Dean did decide to get help, Candy thought that he at least deserved a another chance.''

Tori is now believed to be hoping to get her marriage of almost eight years back on track.

The insider said: ''She is going to forgive him, but will never forget what happened. The real question is going to be if Tori can ever trust Dean again.''

If the couple do decide to split, friends predict a divorce could be very messy.

A source recently said: ''The couple has no prenuptial agreement and Tori is the sole breadwinner.

''Dean wouldn't settle for anything less than joint custody and Tori would be forced to pay him spousal and child support. It's a really sad situation for Tori and the kids.''
