We are in bliss. Thank you for all the love and well wishes — we feel it all! X," she gushed.

Despite being in Hollywood, the "All of Me" crooner admitted he and Teigen sometimes need help with the kiddos.
"There’s so much that I delegate so that I can focus on making music and performing live," Legend previously shared. "Of course, we have help with the kids — nannies, and my mother-in-law lives with us — but we try to focus on what really matters and focus on being where we need to be at the right moments to really enjoy our lives with our kids and make the most of our work life."
