Leona Lewis thinks fatherhood will make Simon Cowell soft

London: The `Bleeding Love` hitmaker Leona Lewis thinks music mogul, Simon Cowell, will be a "good dad" when girlfriend Lauren Silverman gives birth to his first son next year.

"I think he`s going to be a good dad. My brother became really soft when he became a dad, and what happened to him will probably happen to Simon," she said.

Despite Cowell helping guide her career, Lewis now looks to him as more of a "friend" than adviser.

"He`s become more of a friend than a mentor. He likes Jo Malone - maybe I`ll get him a nice big old candle for Christmas."

The 28-year-old star, who will release her fourth album, `Christmas With Love`, later this month is now looking forward to the festive season and says she loves to have a normal relaxed day.
