The 'Today' show will continue their week-long run of country music co-hosts this week with the addition of Kellie Pickler to the lineup. Pickler will fill in for Kathy Lee Gifford this coming Friday (March 23) on the NBC morning program. The 'Tough' songstress will join 'Today' show co-host Hoda Kotb during the fourth hour of the show.

Earlier this week, Josh Turner took over co-hosting duties, while Lee Brice sat in with Kotb earlier this morning (Tuesday). Also coming up as celebrity co-hosts this week will be Randy Travis on Wednesday, March 21.

Pickler's current album, '100 Proof,' has been getting nothing but praise since its release earlier this year. The album has already spawned one hit single, 'Tough,' and she will be working the album's title track as the next single from the critically-acclaimed record.

Following her co-hosting duties, Pickler will head back out on the road with stops in Nevada, New Mexico, Arizona and Minnesota. Click here to see a full list of tour dates where Pickler will be performing throughout the rest of the spring and summer months.
