"He completed his program," Meghan reveals to Country Weekly. "I think it's a real brave thing. He's done really well and stuck it out ... He's got some other commitments to fulfill as part of that, but I'm proud of him. I've just tried to support him, and the fans and the label have been super supportive."
In the meantime, Meghan has kept the couple's performance spots on the Reba tour by bringing along James Otto to fill in for Joshua. "He's got an amazing voice," she gushes of her temporary duet partner. "We've got a really good friendship. Immediately I thought of him [to fill in], because he's got that soul and power in his voice. He definitely fits in on the tour -- he definitely brings in the fun!"
While Joshua may be out of rehab, there's still no word on when he will return to the stage. He did reunite with Meghan to perform for the Linda McCartney tribute concert at the Ryman Auditorium earlier this month. Meghan and James will head to Louisiana and Mississippi for their final shows on the 2011 leg of the All the Women I Am tour. See the tour itinerary here.
