Oh, burn!

Miley Cyrus got personal while taking to Matt Lauer on NBC's "Today" show on Monday, Oct. 7, about her more mature, post-"Hannah Montana" image, as she continues to dominate the entertainment news agenda following a controversial MTV Video Music Awards performance, half-naked "Wrecking Ball" video, and recently, racy photo shoot with photographer Terry Richardson and feud with Sinead O'Connor.

"Is this a phase? Is the sexual side of you that we're seeing a lot of right now something that's gonna be here for a while, then move onto something else?" Lauer asked her.

"I heard when you turn 40, things start to go a little less sexual," she replied.

"Don't say that," he said.

"So probably around 40, around that time, I heard that's when people don't have sex anymore. So, I guess maybe around then," she said.

"Do you know how old I am?" Lauer asked.

"I'm gonna guess 40," she replied.

"I love you! Fifty-five," he said.

"Fifty-five? Oh well you're really, definitely not sexual," she said.

Cyrus also addressed the recent online feud that appears to have erupted between her and Irish pop star Sinead O'Connor. The singer, best known for the 1990 single "Nothing Compares 2 U" -- written by Prince, had in 1992 stirred controversy herself with an "SNL" performance -- in which she ripped a photo of the Pope to protest child sexual abuse by priests.

O'Connor had in an open latter to Cyrus, who performed on "SNL" this past weekend, praised the singer's talent and urged her not to "prostitute" herself for the sake of the music industry. Cyrus had fired back by posting on Twitter a screenshot of O'Connor's 2012 plea for psychiatric help. The singer than threatened to sue Cyrus unless she apologized. She hasn't.

"I think she's an incredible artist," Cyrus said about O'Connor. "I think she's an awesome songwriter and I was really inspired by her for my 'Wrecking Ball' video, which is what started the whole thing. I don't know how someone can start a fight with somebody by saying, 'Hey, I really respect you and I really love what you did. You know what? You suck and I don't like you.' That was kind of crazy, but, you know, as I said, I'm a big fan of hers so it doesn't really matter."

"It's all good," Cyrus added. "You can write as many open letters as you want. That's really what blogging is. I get open letters every day. It's nothing too new for me."
