There to support her? Her dad Joe, sister Ashlee, nephew Bronx – and her boyfriend of several months, Eric Johnson.
"He went and got a sweater and a bowtie to try to lift my spirits because I've been working extremely hard," Simpson, 30, told PEOPLE after the show. "I laughed my butt off!"
She added, "As far as Eric and I go, we're just best friends. He's my dude! I love him."
The couple began dating in May, and ever since have been spotted getting cozy across the U.S. and overseas – even celebrating her birthday together in Italy. If the relationship seems like it's getting serious, that's because it is.
Simpson tells PEOPLE that they're planning to spend Thanksgiving together.
"We're all gonna be in New York," she says. "I'm gonna be on a [Macy's parade] float. It's not always the best way to spend a Thanksgiving, but it's a great way to celebrate. So, maybe I'll just have all families on the float."
For now, Simpson says she and her man are simply enjoying spending time together.
"Tomorrow we're having a long day off," she says. "He loves art. So, we go to art galleries, and he loves photography. It's cool."
"This [relationship] is just normal, thank God," she continues. "He's very, very supportive. [I] couldn't ask for a better man in my life right now."
Which, of course, begs the big question: Is Johnson the one?
"I never go to that because I already went there, so, I'm not gonna jinx my own self," she says. "He's the one for me right now! I'm very happy, I'm in a great place and if right now could last forever, I'd take it."
