TORONTO — To Shania Twain fans who have waited patiently for new music: your day is coming.

The Timmins, Ont., country superstar has announced she will release a new single, "Today is Your Day," on June 12.

The song will first debut on Twain's reality TV show, "Why Not? With Shania Twain," and will then be available for purchase on iTunes at 11 p.m. ET.

It's the first song Twain has written solo in six years.

The song's release coincides with the U.S. finale of Twain's show, which features footage of her marriage to Swiss businessman Frederic Thiebaud.

The episode won't air in Canada until June 17 on the Oprah Winfrey Network, but a spokesperson for iTunes confirmed that Canadians would have access to the new song at the same time as customers in the U.S.
