Lori Loughlin's daughters, Olivia Jade and Bella Giannulli, posted on Instagram for the first time since the Varsity Blues college admissions scandal broke earlier this year.
The 19-year-old and 20-year-old sisters shared photos of themselves with their actress mother and wished her a happy birthday in the captions.
Loughlin, who pleaded not guilty to charges of conspiracy to commit mail fraud, among others in April, turned 55 on Sunday.

"Happy birthday mama. I love you," added Isabella.
Court documents unsealed on March 13 revealed that Loughlin and and her husband, fashion designer Mossimo Giannulli, "agreed to pay bribes totaling $500,000 in exchange for having their two daughters designated as recruits to the USC crew team -- despite the fact that they did not participate in crew -- thereby facilitating their admission to USC."
Emails from Loughlin and a recorded conversation between her and her husband, which were obtained by federal agents, implicated them in the scandal, dubbed "Operation Varsity Blues," according to documents.
The couple was indicted on a federal charge of conspiracy to commit mail fraud and honest services mail fraud, a crime that could get them each a maximum 20-year prison sentence if convicted. They were later hit with additional charges, including a count of conspiracy to commit money laundering, according to federal officials. They have pleaded not guilty.
