"Her friends and family have been incredibly supportive of her relationship with Josh," a source tells PEOPLE of Kevin Costner's ex-wife

Christine Baumgartner is engaged to boyfriend Josh Connor nearly one year after finalizing her divorce from Kevin Costner.

After finding love with Costner's former friend and wealthy financier Josh Connor, a source told PEOPLE that he proposed on January 26 in Santa Barbara. She reportedly thought it was just an "intimate dinner." "It was about to rain, so almost no one else was on the beach when Josh got down on one knee," the insider explained.
