FIRST LOOK: See Carrie Underwood as a Sexy Flight Attendant!


She loves to fly, and it shows!

As previously reported, country singer Carrie Underwood makes her sitcom debut in March on CBS' How I Met Your Mother.

Show regular Neil Patrick Harris posted a TwitPic of him with Underwood from the set. As womanizing character Barney, Harris is sure to ogle Underwood -- dressed in a retro flight attendant's outfit, complete with an upswept 'do, white boots and a polka-dotted scarf!

"This week's awesome guest star: . HIMYM - You'll Love The Way We Fly! " reads Harris' caption, suggesting a saucy airline theme.

2010 promises to be a fab year of firsts for Underwood, 26: her first sitcom appearance and a wedding to fiance Mike Fisher sometime this summer.
