New mom Blake Lively will flip when she hears husband Ryan Reynolds is secretly getting parenting advice from former flame Sandra Bullock, close friends tattled.

“Blake is insanely jealous of Ryan and Sandy’s bond,” a Reynolds source exclusively told The National ENQUIRER. “So he dared not tell Blake that he reached out to Sandy.”

Ryan sought Sandra’s advice because she’s been a model mom to her five-year-old adopted son, Louis, and because he’s clueless about kids, friends said.

“Ryan wanted a crash course in what harsh realities to expect when he becomes a dad,” an insider said.

But the same friends fear the “Green Lantern” hunk is walking on thin ice!

“After Blake and Ryan married, she forced him to cut off communication with Sandy,” one friend said. “She’ll be furious to learn that Ryan and Sandy are talking behind her back!”

Sandra, 50, and Ryan, 38, were romantically linked when they co-starred in the smash 2009 rom-com, “The Proposal.” While Sandra denied they were dating, insiders claimed she was crushed when he wed Blake.

And friends fear the 27-year-old “Gossip Girl” star, will lose it when she learns how Sandy reacted to Ryan’s request for help.

“Sandy offered to let Ryan stay overnight at her house so he could witness first-hand life with a toddler, including the temper tantrums, thrown food and bed-wetting accidents,” dished the insider.

While Sandra has provided Ryan with great parenting advice, Blake will never take it in the spirit it was given, sources said.

“It’s as if Blake is insecure and threatened by both Sandy’s success and the spell she once cast on Ryan,” added an insider.
