"She's lovely," Alan Thicke told E! News at the "Vacation" premiere in Los Angeles. "It's a great time for him. [He has an] album coming out and April is there and supportive."
The 18-year age gap between the 38-year-old "Blurred Lines" singer and his 20-year-old model girlfriend doesn't seem to be much of an issue either.
"The apple doesn't fall far from the tree," Alan's wife, Tanya Thicke, told E!
That's because at 40, Tanya is 28 years younger than Alan, her husband of 10 years.
"I wouldn't expect anything less," Tanya said.
She was quick to add, "I think it's also very important that she's also very mature. I think that says a lot. She's a very mature young lady. A very beautiful, smart, mature young lady."
Said Alan, "We like her a lot."
