When E! News caught up with the native Texan at the Frozen premiere on Tuesday, Nov. 19, in Los Angeles, she couldn't hold back when asked about the 54-year-old.
"I don't know, he's gotten really boring," the 21-year-old blue-haired singer quipped, without missing a beat, while trying to answer whether or not Cowell is stepping up to be a father by selling his bachelor pad.
Sounds just like old times with these two.
"I don't have any advice to give to someone who has lived like a hundred more years than I have," Lovato exclusively told E! News in August when asked if she's given Cowell tips on how to handle the scrutiny surrounding his personal life. She jokingly continued, "I mean, I might be off by a few, so maybe 110. But I have a lot of fun with him and he's a great guy. He'll be good."
Lovato looked chic as she hit the red carpet, sporting a black dress, black heels and her new bright 'do.
The X Factor judge's song, "Let It Go," is featured on the Disney flick's soundtrack. Lovato also dished about her new music video, "Neon Lights."
"I found a way to make my grown up video," Lovato revealed. "Definitely more sexy and um, more mature but I also stayed covered up which was good, and I danced, and I had blue hair."
