Demi Lovato is headed to Iowa to campaign for Hillary Clinton.

The Des Moines Register reports the 23-year-old "Confident" singer is slated to join the 2016 Democratic front-runner on the campaign trail at an University of Iowa event on Jan. 21. The former first lady is currently locked in a back-and-forth battle with Vermont Sen. Bernie Sanders in that critical, early voting state.

Lovato thus joins a group of celebs, including fellow pop star Katy Perry, who have not only endorsed the former secretary of state as President Barack Obama's successor, but have publicly come out to campaign for her.

Perry previously also campaigned in Iowa for Clinton, joining the candidate and former President Bill Clinton on a Des Moines stage. "Girls" star Lena Dunham and soccer star Amy Wambach have also joined Hillary Clinton on various campaign outings.

Meanwhile, Lovato also recently celebrated her sixth anniversary with "That '70 Show" boyfriend Wilmer Valderrama.

According to Us Weekly, Lovato started dating the now 35-year-old Valderrama when she was 17-years-old, just as she was embarking on one of the most sobering times of her life. Not long after they became an item, she entered rehab for both substance abuse and mental health issues.

These days, the two have become one another's biggest supporters, and their relationship appears stronger because of it. After remaining relatively private about their affairs, the two have opened up about their union in recent days and have become much more open in expressing affection.

Lovato has long expressed gratitude to Valderrama for "saving" her.

"He never takes credit for my sobriety, but I guarantee I wouldn't be alive without him today," Lovato recently told "HuffPost Live."

She later added, "I was dealing with bipolar depression and didn't know what was wrong with me. Little did I know, there was a chemical imbalance in my brain. Because I didn't tell people what I need, I ended up self-medicating and coping with very unhealthy behaviors."
