Barack Obama is celebrating his 30th wedding anniversary with another heartfelt message to his beloved wife Michelle. The former president went to Twitter on Monday to commemorate the special day with sentimental words and a pair of classic photos.

One of the pictures shows the couple enjoying their vacation together, while the other photo captures the pair smiling gleefully on their wedding day.

“Miche, After 30 years, I’m not sure why you look exactly the same and I don’t. I do know that I won the lottery that day— that I couldn’t have asked for a better life partner. Happy anniversary, sweetheart!” the 44th president wrote.
