SALT LAKE CITY — Lori Loughlin’s daughter Isabella Rose Giannulli quietly deleted her Instagram the day after her mother Lori Loughlin pleaded not guilty on federal charges, according to E! News.

“It’s a mystery why Bella Rose just now decided to delete her account, although the timing to the latest development in the case is certainly interesting. What’s more, the Daily Mail is ambiguously reporting that one of Loughlin’s daughters is now the focus of a Department of Justice probe for her involvement in the college admission scandal,” according to Uproxx.

The unconfirmed report, which cites “sources,” says that Loughlin’s daughter receive a letter from federal prosecutors that she was a subject of an investigation, Uproxx reports.

Loughlin and her husband Mossimo Giannulli were accused of paying $500,000 in bribes in exchange for having their daughters become crew team recruits for the University of South California.

Her sister, Olivia Jade, still has an active account. Olivia Jade is a popular YouTube and Instagram personality.

A source told E! News that Olivia Jade "is very distraught and is in crisis mode."

"Olivia is more embarrassed than anything and doesn't know how to handle all of the stress and scrutiny that has been surrounding her and her family," the source continued. "She feels completely lost."
