Dancing with the Stars' sixteenth-season celebrity participants have reportedly begun to leak out.

TMZ has reportedly confirmed The Bachelor star Sean Lowe, former American Idol finalist and country singer Kellie Pickler, 2012 Olympic gold medal winning gymnast Aly Raisman, and country singer Wynonna Judd will be four of the celebrities competing on Dancing with the Stars when its sixteenth edition premieres on ABC next month.

An ABC representative declined to comment when contacted by TMZ, noting the network will formally announce Dancing with the Stars' sixteenth-season cast Tuesday morning on Good Morning America.

"We do not comment on casting rumors, but tune in to GMA on Tuesday when we reveal the cast live!" the representative said.

Us Weekly had reported Lowe would likely be one of the celebrities competing on the next season of Dancing with the Stars earlier this month. 

Lowe would be the second Bachelor and fourth The Bachelor franchise participant to compete on the reality dancing competition, following in the footsteps of former The Bachelor star Jake Pavelka, former The Bachelorette star Trista Rehn, and former The Bachelor bachelorette Melissa Rycroft

After intially finishing in third place on Dancing with the Stars' eighth edition in 2009, Rycroft returned and won last fall's All-Stars edition with professional partner Tony Dovolani.

According to prior reports, Dancing with the Stars producers were also interested in having former The Bachelorette star Emily Maynard -- who dumped Lowe when he competed for her heart on last year's edition of female-fronted spinoff of The Bachelor -- be part of upcoming season's cast.

While several former American Idol finalists have performed on Dancing with the Stars over the years, Pickler, a former fifth-season finalist, would be the first Idol alum to compete as a celebrity contestant.

Dancing with the Stars' sixteenth season will premiere Monday, March 18 at 8PM ET/PT on ABC -- one week after the finale of Lowe's The Bachelor edition airs in the same time period on March 11.
