She can't stop — collecting! In a new interview, Miley Cyrus opened up about keeping a bag of Southwest Airlines peanuts for 15 years — and the reason is just too sweet.

"They represent the beginning of this life for me," she said during a Jimmy Kimmel Live appearance this week. "Because [I was] on my way to LA for the first time to audition for Hannah Montana, and actually, I believe my dad [Billy Ray Cyrus] was there. He was in first and I was in coach, and he said he'd throw me a hot peanut from the classy section. I said, 'I already have my own!' I kept them with me forever." Clearly, the Disney alum doesn't forget where she came from.

Miley also joked that her fiancé, Liam Hemsworth, called her a "hoarder" for holding onto items like this, though she insisted she's actually "collecting." She told host Jimmy Kimmel, "That thin line that divides hoarding and collecting is keeping things in the package." Hopefully they find a way to compromise — considering In Touch revealed they secretly got married in October!

A source spilled that the couple tied the knot on Tybee Island in Georgia — where they first fell in love while filming their 2010 flick The Last Song. "Neither Miley nor Liam planned to get married when she booked the trip to see him, but that all changed once she arrived," said the insider. "They felt so nostalgic and spent hours reminiscing about old times. They both realized that the island was the ideal setting because it has such sentimental value to them."

Miley and Liam first got engaged in 2012, but decided to call it quits in 2013. Fast forward to December 2015, and the "We Can't Stop" songstress was spotted in Liam's native Australia spending time with The Hunger Games star's family. She finally confirmed they got re-engaged in October 2016 with an Instagram photo flashing her diamond ring. Now, we're just waiting for little baby "collectors!"
