Felicity Huffman Flower Power Pulls Me Through ... Olivia Jade All Smiles Too

12:30 PM PT -- There was another person tied to the college scandal that was all smiles this weekend -- one Olivia Jade. She wasn't graduating or anything but was certainly in a celebratory mood.

Lori Loughlin's youngest daughter was seen Saturday with a giant grin on her face as she left a nail salon in Beverly Hills. She wasn't all that dressed up for the occasion -- wearing an over-sized leather jacket, ripped jeans and green flip flops that looked two sizes too big.

Either way, it's clear she's still not sweating her parents' legal case -- which, as far as we know, they're ramping up to fight in court after pleading not guilty to a slew of charges.

Despite the fact Olivia might eventually be called to the stand to testify, you'd never be able to tell there was trouble on the home front by the way she's carrying herself here ... or here, or even here.

Fake it 'til you make it, we suppose.

Felicity Huffman's doing something we have seen since her indictment in the college admissions scandal, and that's ... smiling.

You could say she stopped to smell the roses -- although they look more like lilies -- Saturday in West Hollywood. Felicity's bouquet purchase comes just as her daughter, Sophia Grace, graduates high school. We don't know if the flowers were for Sophia, but Felicity looked pleased with her selection.

Federal prosecutors say Felicity paid Rick Singer $15k to rig Sophia's SAT scores ... by giving her extra time on the test and then correcting some of her answers. We've seen a very somber Felicity at her court appearances in Boston ... including the one where she agreed to plead guilty.

Felicity and William H. Macy have said Sophia knew nothing about the scheme. Felicity's scheduled to be sentenced in September ... and could get anywhere from zero prison time up to 4 years.

For now, she and Macy seem to be focusing on the positive -- Sophia's high school graduation.

College is a whole other Oprah.
