I thought, ‘Wow, she feels super bad for me!’” he previously told Billboard about his girlfriend, who was going through a divorce from Gavin Rossdale at the same time he and Lambert were splitting.
“It went from that, to checking in on each other once a week through email – ‘This s— happened to me, what happened to you?’ – to maybe three times a week, then every day, to ‘Hey, here’s my phone number if you ever want to text.’ Next thing I know, I wake up and she’s all I care about, and I’m wondering if she feels the same about me,” he said about falling for the mom of three.
“Who else on earth could understand going through a high-profile divorce from another musician?” he added. “You can’t even imagine the similarities in our divorces.”
