The 39-year-old singer recently began dating his fellow 'Voice' coach - who split from husband Gavin Rossdale in August - and has "tons of reasons" to be grateful she's in his life.

He said: "I'm thankful for Gwen for tons of reasons, but mostly because she makes us all look a whole lot better on this show."

The 46-year-old beauty sang new single 'Used to Love You' on 'The Voice' last night (30.11.15) and the 'Sangria' singer - who separated from wife Miranda Lambert earlier this year - was in awe of the stunning white gown she donned for the performance.

Speaking to 'Entertainment Tonight' before the episode of the talent show aired on NBC, he gushed: "Wait til you see! I saw what she's going to be wearing for this performance tonight, it's stunning. It's so beautiful."

Meanwhile, fellow coach Pharrell Williams thinks the couple's new relationship is good for both of them, both personally and creatively.

He said: "I am grateful that Gwen is in the most free place that I feel like she's ever been since I've known her as a human being.

"Not just creatively, but just as a human being, she's floating right now.

"I'm grateful that Blake is smiling these days and inspired as well musically."
