“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,” Sara told Us. “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.”

Erin joked about her dad’s new relationship in September, posting a photo of the new couple of Snapchat, with the caption, “Excited about my new step mom,” and writing “My parents” on a video of the Scorpion actress performing while accompanied on the piano by David.
