Carrie Underwood and Scotty McCreery have enjoyed long careers since winning American Idol during their respective seasons. The country music winner from Season 15 has not.

Trent Harmon vacated social media for 17 months after splitting from his post-Idol record label. After turning up last summer, it's been a steady diet of photos of him with his dog. However, there are signs that Harmon is remaining active in country circles — scroll down to see what the 31-year-old from Mississippi is up to today.

This list of American Idol fan-favorites who disappeared like smoke on a windy day also includes a runner-up and a third place finisher, plus two charismatic North Carolinians who achieved early success on country radio before stepping out of the spotlight. What is Bucky Covington up to? How about Kellie Pickler? Casey James is actually back, but you might not have noticed, because he's a part of a Texas country reality television supergroup.

Most shocking about this list of artists is that many are over 40 years old, which means we're all getting old. Check out seven Idol updates, or tap play on the above video if you prefer moving pictures and talking.

Carrie Underwood invested her money wisely after winning American Idol in 2005. One of her first big purchases was a 3,099-square-foot home in the well-to-do Nashville suburb of Franklin, Tenn. Underwood paid $384,000 for a luxurious 3-bedroom, 3.5-bathroom stone and stucco home in a private gated community.

The house features a library, a vaulted ceiling and lovely amenities throughout, but while it's very nice, it's certainly not the kind of home you'd picture for a budding country superstar. Underwood wound up being a huge success right out of the gate with her debut album, Some Hearts, and she sold the home in Franklin for $372,500 in 2007, when she purchased the Brentwood mansion that she would later share with her husband, Mike Fisher.
