And simply click this link to be taken to his blog's feed of the chat, where you can participate in this once-in-a-lifetime event, during which you will be able to ask Mahone questions, which he will respond to in real time.

The live chat event, which has been hyped via Twitter under the #austinmahonechat hashtag for the past few days, begins at 7 p.m. Tuesday, and the moment has finally arrived when you can meet Mahone for yourself. Mahomies will be tuning in from around the world, so be sure you don't miss out.

Mahone is not the world's best known pop singer, but following his first YouTube videos, which he posted in 2010, he built a massive online following and has been called the "second coming of Justin Bieber" by the Houston Chronicle, because their rises to fame are so similar. He even covered Bieber's song, "Mistletoe" in October 2011, and his cover got more views than Bieber's original.

The Texas singer-songwriter was finally signed to a major label - Chase/Universal Republic Records - in August 2012, according to Billboard.

His first single, "11:11," hit No. 19 on the Billboard Heatseekers Songs chart, and his second single, "Say Somethin'," hit No. 34 on Billboard Pop Songs chart.
