All you "Smilers," we have a little secret of Miley Cyrus for you. The 20-year-old songstress has revealed the real reason for why she is being so sexual these days.

The "Wrecking Ball" singer believes she only has 20 more years for doing the naughtiest things she can and wants to do the maximum she can in these years.

Her raunchy MTV Video Music Awards performance catapulted Cyrus to become the hottest female today. However the singer that left your tongues wagging and eyes popping told "Today's" host Matt Laurer on Monday that she will stop doing this sexy-crazy stuff when she turns forty.

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

So when will this "Wrecking Ball" madness and nudity stop in Miley's life?

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

Miley's one liner seemed to catch the much older host Lauer off guard and he asked whether Cyrus knew how old he was to which the "We Can't Stop" star guessed 40.

Lauer however answered smilingly that that he is 55.

"Well, then you're really, definitely not sexual," answered the in-your-face Miley leaving the host embarrassed.

Miley Cyrus also opened up about her ongoing feud with Sinead O'Connor.

"I think she's an incredible artist, I think she's an awesome songwriter, and I was really inspired by her for my Wrecking Ball video, which was what started the whole thing," Cyrus said.

Miley, who was dressed in her raciest best also said that she really respects O'Connor and all the controversy does not bother her.

"I don't know how someone can start a fight with somebody who said, 'Hey, I really respect you. And I really love what you what you did.' 'You know what? You suck! I don't like you!' That was kind of crazy. But as I said, I'm a big fan of hers, so it doesn't really matter. It's all good," Miley added.
