Molly Sims is beyond ready to meet the newest addition to her family.
The Las Vegas alum, who is expecting her third child with husband Scott Stuber, attended George Clooney's Casamigos Tequila Halloween party at a private residence in Beverly Hills, California, on Friday, where she told ET’s Brendon Geoffrion she's in the process of brainstorming names for the baby.
"I love [the names] Stella and Ruby and Marlow and Mya and Mia," she said. "And if it's a boy, I love Wesley and Finley and Dutch and Wilder. I have so many. My husband's addicted to Nameberry, so he literally makes like a PowerPoint presentation."
They will be able to shorten that list in half soon, however.
"We're not there [yet], but we're going to find out [the gender] in a week," she gushed to ET. "We weren't going to do it, [but] I can't stand it."
Sims and Stuber, who are also parents to 4-year-old son Brooks and 1-year-old daughter Scarlett, announced they were expecting again via an adorable video posted to the actress' YouTube channel in August. "This is happening. This is like our Hail Mary," Sims exclaimed. "We can't wait to meet you!"
Meanwhile, at Kate Hudson's Halloween bash, which Sims also attended, Katy Perry was barely recognizable as Democratic presidential candidate Hillary Clinton. Her boyfriend, Orlando Bloom, was also in attendance, dressed in his best Donald Trump get-up.
