As we previously reported, on Tuesday, July 3 David and Katharine announced their engagement after a year of dating.

Back in December 2017, Sara exclusively told Us Weekly that she and her siblings were happy for their father being in a relationship with the singer.

She said at the time,

We approve of whoever is going to be good to my dad; at the end of the day and we’re very honest about it. If we ever thought that anyone was in something for the wrong reasons, we would be very vocal about it. We just want someone that’s going to treat him well and that cares about him, and I think he’s with someone right now that really does.

In September, Erin, meanwhile, joked about David's new relationship, posting a photo of the new couple of Snapchat captioning, “Excited about my new step mom,” and writing “My parents” on a video of Katharine performing while accompanied on the piano by her husband-to-be.

The relationship rumors of the couple were first surfaced in May 2017 after they were spotted cuddling up in Malibu.
