"I'm looking for someone who's going to change the world with me," Michelle says in the promo. "I'm ready."
The promo begins with The Bachelor star Matt James' runner-up walking through a room adorned with flowers while wearing a fit and flare jacquard ivory gown with a high slit that hugs her curves. Michelle wore her hair down curled and spiced her dress up with a gold belt.
As the song "Bounce Back" plays, Michelle enters a basketball court, dribbles a basketball and then sinks a shot in a hoop made of a crystal net.
She then proceeds into a classroom, where Michelle grabs a red apple and tosses it into the air with a sexy smile.
After stepping down a staircase lined with gorgeous flowers, Michelle grabs a rose and strikes a pose.
Michelle's season reportedly began filming on July 30 and is expected to conclude around September 10.
Michelle and her cast of guys reportedly moved into the Renaissance Esmeralda Resort & Spa in Indian Wells, CA, and traveled to Michelle's home state of Minnesota, where they stayed at the Marquette Hotel.
In a departure from the franchise's other recent seasons that have filmed amid the coronavirus pandemic, Michelle and some of her bachelors will also reportedly get to travel to more places than just California and Minnesota for hometown dates and Fantasy Suite dates.
Michelle showed up late on Matt's The Bachelor season following the third Rose Ceremony but established an instant connection with him.
Matt eliminated Michelle from The Bachelor's 25th season in second place, and then Michelle was announced on After the Final Rose in March as one of two The Bachelorette stars -- along with Katie -- for back-to-back seasons in 2021.
Michelle admitted she was absolutely crushed and "not okay" when Matt chose to eliminate her after she met his family at the end of the process.
On After the Final Rose, Michelle recalled the moment when she first found out she'd be starring on the franchise later this year.
"I would be lying if I didn't say when they first told me, I thought we were going to be the Bachelorette at the same time," Michelle shared.
"And so, I was a little nervous, but once I found out it was two different seasons, I was here for it! I'm excited that I have somebody to bond with over this and share notes as we go."
Given Michelle had seemingly fallen head over heels for Matt, After the Final Rose host Emmanuel Acho asked Michelle if she was ready to try to find love once again.
"I am ready... I really do think that this process works," Michelle explained.
"When you can [cast] out all of these outside distractions and really dive in, I think you can learn a lot about somebody. I'm just excited. I'm ready to get started!"
Season 18 of The Bachelorette is scheduled to premiere Tuesday, October 19 at 8PM ET/PT on ABC.
