They went public with their relationship after David’s daughter Erin Foster has shared a snap of them together in Los Angeles in September 2017. Erin has captioned the shot, “Excited about my new stepmom.” The couple has spent a rare red-carpet appearance at the Elton John’s annual Academy Awards Viewing Party sponsored by Bulgari in Los Angeles. The former “American Idol” stunned the look in a semi-sheer lacy black dress which featured ruched detailing in the front, such as a butterfly design.

She has pulled back her brunette sleek tresses into a tight bun with a few locks at the front whereas the Grammy-winning producer was dressed in a classic black suit with a partially unbuttoned white shirt underneath with no tie.  The pair has been friends for years and their first meeting was on the set on the “American Idol” when Katharine was a contestant in 2006. Katharine has earlier told PEOPLE that she has “zero desire” to address them, when she was asked about her relationship rumors. She has said that it’s great that they want to do that and she thinks it’s so amusing that people are amused by her love life.”

The 33-year-old star shared, “I’m not doing anything wrong, so whether people think it’s true or false, I don’t, you know, there’s nothing bad happening in my life, so people can just say whatever they want.” Katharine has given a sneak peek to her Oscars prep on her Instagram stories by giving all the credits to her stylist Monica Rose, hairstylist Ericka Verrett as well as makeup pro Amy Strozzi for her look for the Oscars. The couple already has the approval from Erin Foster and Sara Foster. A source has earlier told E! News that the pair is enjoying the bond that they share right now. The insider has shared, “Their relationship is very healthy and in a good place.”
