While the colorful poncho and baggy olive-green pants may not be a far cry from the bohemian chic attire she regularly dons, it's been quite a while since we've seen Cyrus sport her famously long, blonde tresses ever since she traded them in for a pixie cut in August 2012.
An eyewitness tells ET that the rural set was small and quiet, with only two cast members (Cyrus and her co-star, The Big Short actor John Magaro) and a crew of 30.
In the scene they were filming, Cyrus was seen picking daises near a sun dial in the backyard of a house as Magaro approached her and suggested they go on a walk through the woods, the eyewitness added.
It was apparently a hot day on set, but that didn't stop a relaxed Cyrus and Magaro from filming. The source told us they shot for about 10 hours, from 9 a.m. to 7 p.m., with a break for lunch. Cyrus ate a veggie wrap and was joined by one of her gal pals.
Allen's first-ever TV project, which has yet to be titled, takes place in the 1960s and will be comprised of six half-hour episodes. In addition to Miley and Magaro, Allen will also star in the series, along with Elaine May and Rachel Brosnahan.
This marks the former Disney star's first regular acting gig since her recurring role as Missi on Two and a Half Men back in 2012. As we patiently wait to hear more on the series set to premiere later this year, watch the video below to get up-to-date on Cyrus' rumored rekindled romance with her former fiancé, Liam Hemsworth.
