Isabella, 21, and Olivia Jade Giannulli, 20, are said to be “proud” of their parents for pleading guilty in the college admissions scam but are preparing themselves to see their mom and dad locked up, an insider told Us Weekly.

“It will be surreal for Isabella and Olivia to visit them behind bars,” the source said, “but this is a much better outcome than what they envisioned.”

The former “Full House” star, 55, agreed to serve two months in jail, pay a $150,000 fine and perform 100 hours of community service in exchange for pleading guilty to one count of conspiracy to commit wire and mail fraud.

“As embarrassing and awful as it’s been, Olivia and Isabella still love their mom deeply,” the insider told the magazine, “and it pains them to see her suffer.”

Loughlin’s 56-year-old fashion-designer husband, who founded the popular Target brand Mossimo, copped to two counts — conspiracy to commit wire and mail fraud and honest services wire and mail fraud. He agreed to serve five months behind bars, pay a $250,000 fine and do 250 hours of community service.

The pair reportedly opted to plead guilty because a trial “would just be reckless.”

The couple admitted to paying $500,000 in bribes to convicted college fixer William “Rick” Singer, who got their daughters into USC as rowing recruits — even though neither participated in the sport. The Feds eventually released the photos of Olivia and Isabella that were allegedly used to scam the duo’s way into the California school.
