"I haven't [reached out to Bullock]. You know, she's got a lot on her plate," McGraw, 42, tells Entertainment Tonight Canada in an interview airing Friday. "I just wish her nothing but the best."
McGraw, who spoke to ET Canada Thursday in Vancouver before his concert, added that Bullock, 45, can weather this marital storm. "She's tough," he says. "I'm not that tough."
On the professional front, McGraw praises Bullock as a great teacher and coworker. "She's such a professional. She's so great. I've learned a lot from her," he says. "We certainly got friendly. She's a very friendly person. A really nice person."
As for Bullock's Best Actress Oscar win for The Blind Side, he says, "It's such an elusive trophy, but her performance was so good that it was just so hard to overlook that."
