The gorgeous new bling is a gift from Pratt, and features a massive oval-cut stone surrounded by a halo of diamonds set on a gold band. Faris, looking like a true princess in a stunning lavender lace Reem Acra gown with a crystal-accented neckline, was all smiles while showing it off as she and Pratt posed for photographers.

The ring is noticeably larger than the original one Faris received from Pratt when he proposed to her in 2008, before tying the knot one year later.

"[Chris] just got me this ring. I know. Like two days ago," Faris told E! News. "I look [at it] and I'm like, 'I can't believe it either!' He's an incredibly romantic man and I'm very, very lucky."

"She got me a tractor," added Pratt. "So we're kind of even!"

Interestingly enough, the Mom star received the gift just a few weeks after she opened up about her marriage with Pratt on her podcast, Anna Faris Is Unqualified, while chatting with fellow actress Isla Fisher.

"We grapple with the idea of being a public couple," Faris explained. "For the first time, maybe a year ago or 10 months ago, we were in the public a little bit. There were some tabloid rumors about strain on our relationship."

"I just remember feeling so hurt in a way that bothered me because I didn't want to think of myself as somebody that could be affected by tabloid s**t," she continued. "There's a picture of me walking alone on the beach -- aging Anna Faris, alone on the beach."

"I take pride in how great my relationship is with Chris, but, having said that, of course, in this crazy world where he's off doing movies and I'm in L.A. raising our child [4-year-old Jack], of course I'm going to feel vulnerable, like any normal human would," she added. "It did make me feel like, 'Is public perception -- even though it's false -- is there a grain of something?' It made me feel incredibly insecure."
