OK! Exclusive: You Won’t Believe Who Katie Holmes Has Looking After Her Daughter!

Not to fear, Katie Holmes’ sister is here! Aside from her dad Martin, there’s one person Katie will always be grateful for – her older sister Holly Ann, who’s become a very significant person in her niece Suri Cruise’s world.

“Holly’s always been the most mature of Katie and her siblings but that doesn’t mean she’s no fun when it comes to Suri,” an insider exclusively revealed to OK!.

“Holly was instrumental in helping Katie get Suri back on some kind of normal path after Kate’s divorce to Tom Cruise and has been very active as a ‘step-in parent’ for Suri,” the sourced dished. “She helped her find the right school in New York and looked after Suri while Katie shopped for an apartment.”

While Suri is just 11-years-old all of what her aunt does for her isn’t lost on the pre-teen.

“Suri adores every one of her mom’s family, but she has a special place in her heart for Holly, who’s become very hands-on with Suri since her own kids have grown up,” said the insider.
