"You are the best. period," the YouTuber, 21, shared on Instagram, along with a black-and-white throwback photo of the Full House actress. Meanwhile, her sister, 22, shared camera film stills of herself, Olivia and their mother, writing: "Mama bear."
Loughlin, who shares Olivia and Isabella with husband Mossimo Giannulli, served nearly two months in prison last year for her involvement in the high-profile college admissions scandal. After being admitted in October 2020, Loughlin, 56, was released from the federal correctional facility in Dublin, California, in December.
Giannulli, 57, was also implicated in the scandal and was released from home confinement last month, marking the end of his five-month sentence. He was booked into federal prison on Nov. 19.
In May 2020, Loughlin admitted to one count of conspiracy to commit wire and mail fraud, while Giannulli pleaded guilty to one count of conspiracy to commit wire and mail fraud and one count of honest services wire and mail fraud.
According to the criminal complaint against them, the couple was accused of paying $500,000 to Rick Singer and Key Worldwide Foundation to falsely designate their two daughters as recruits to the University of Southern California crew team, even though neither ever participated in the sport.
On Aug. 21, a judge approved the couple's plea deal, sentencing her to two months in jail, a $150,000 fine and 150 hours of community service, while Giannulli received five months in jail, a $250,000 fine and 250 hours of community service.

Following Giannulli's April release, a source told PEOPLE that the couple were both feeling "beyond relieved."

The insider added, "Lori is a wonderful wife, mother and friend. She and Mossimo made huge mistakes. They have taken responsibility for them and just want to start fresh now."
