"Just want to wish Billy Ray Cyrus the most special, magical birthday ever," Reynolds joked, referring to the fact that today marks the country star's 55th birthday. "I love you with all my heart. Also, Happy Birthday to my wife."

Reynolds, 39, has been married to Lively since September 2012. The gorgeous couple has one daughter together, 1-year-old James, and is expecting baby number two soon. In April, a source close to the former Gossip Girl actress confirmed to ET that she's pregnant again.

ET talked to Lively in June, when she revealed that her hubby helped her get bikini ready for her role in The Shallows just 10 months after giving birth to James. He also read the script before her and gave his instant stamp of approval.

"He was very kind and generous to do that," Lively said. "I was really sick [at the time] and I was working, and so he read it and he was like, 'Aww the action is amazing.'"
