Lori Loughlin Putting on a ‘Brave Face’ Amid Mossimo Giannulli Split, But Actress Is ‘An Absolute Mess’

The ceiling is caving in on former Full House star Lori Loughlin — friends reveal she’s on the verge of a breakdown from her highly publicized split from hubby Mossimo Giannulli after 27 years of marriage.

Lori, 61, had hoped the couple’s separation was simply a break but was crushed when Mossimo, 62, made it clear the arrangement was permanent, say pals.

“Lori’s doing her best to put on a brave face, but the scale of heartbreak and humiliation is on another level — Mossimo has totally checked out of the marriage,” says a source.

Still, an insider close to Lori insists “there will be no breakdown” and that she “is a strong woman and will get through this with the help of loved ones.”

The fashion designer and the sitcom siren seemed solid before their marriage collapsed under the weight of the 2019 Varsity Blues scandal, in which they were each convicted of using bribes to get daughters Olivia Jade, now 26, and Isabella, 27, into the University of Southern California.

After pleading guilty, Lori served a two-month prison term while Mossimo did a five-month stretch. The couple was fined $400,000.

A source tells the National Enquirer that Lori “did everything” to repair the marriage after the scandal — but word surfaced in early October that the duo had separated, and an insider says they were living apart for months.

While it was Lori who initiated the split, “she thought that if she and Mossimo took a break, they would realize how much they mean to each other and get back together stronger than ever,” says a source.

“But Mossimo left Lori in L.A. while he’s been staying at their other home in Idaho, and even when he flies back for business, he doesn’t check in on her. He’s given her no indication he ever wants to reconcile, and she’s crushed.”

And Mossimo has recently been seen out with 32-year-old fashion stylist Hannah Harrison, though she insists they are just “good friends,” per US Weekly.

“Lori is in a state of bewilderment because it’s so hard for her to comprehend how he’d be this callous,” says a source.

“She feels shattered and can’t stop crying. She’s an absolute mess and her friends and daughters are incredibly worried. They want her to seek help before she goes off the deep end.”
