Dancia McKellar and Candace Cameron Bure are battling it out on the new season of “Dancing with the Stars,” but it’s not the first time these two former child stars have faced off.

According to Us Weekly, the sitcom stars once competed for the attention of fellow child star Jeremy Miller, who appeared on “Growing Pains.” The magazine reported Bure confronted McKellar behind the scenes, ahead of the ABC competition series.

"Candace had a run-in with Danica and told her she was the reason she split with her old boyfriend," a source told Us Weekly. "…[Miller] broke up with her to date Danica."

The source said the exchange was all in good fun.

Bure is now married to hockey player Valeri Bure and McKellar is currently single.

They're both dancing on the 18th season of "Dancing with the Stars."
