Lambert 'trying to process everything' post Shelton split?

Los Angeles: Country star Miranda Lambert is reportedly sad and trying to process everything after her divorce from Blake Shelton got finalised.

The two stars called it quits after 10 years of marriage. As Miranda Lambert's fans continue to express shock that her marriage to Blake Shelton has ended, the singer is staying focused on putting one foot in front of the other.

"She's doing the best she can and taking it day by day," a source said of Lambert, who fell for Shelton after performing with him for a concert special in 2005.

Rumors of trouble in their marriage had dogged Shelton, 39, and Lambert, 31, since their 2011 wedding, but the source says the finalisation of their divorce has left Lambert "sad and trying to process everything."
