The former president shared some birthday cheer in honor of Biden's 80th on Sunday, with a tweet featuring a wholesome throwback photo of the two U.S. leaders.
"Happy birthday, @JoeBiden," Obama wrote. "There's a lot to celebrate these days, and I couldn't be more grateful that America has you sitting behind the desk."
Obama wasn't the only leader to share the love with his former right-hand man. First Lady Jill Biden, who has been married to the commander-in-chief since 1977, shared a heartfelt tribute to her husband on Sunday, along with some touching images of the pair dancing together.
"There's no one else I'd rather dance with than you," Jill shared. "Happy Birthday, Joe! I love you.💕"
The first lady also shared an adorable picture of the family together for Biden's birthday.
"A perfect birthday celebration filled with so much love — and Joe's favorite coconut cake!" she captioned the picture.
While Biden is ringing in his 80th year, he continues to hold the title of the oldest sitting U.S. president, beating Ronald Reagan, who was 77 at the end of his time in office. Reagan took office at 69 years old and served two terms, while Biden took office at 78 — automatically setting the record when he stepped foot in the White House after his 2021 inauguration.
Also toasting his 80th year, Hillary Clinton posted a silly photo of Biden posing near former President Obama.

For her dress, Naomi wore a custom Ralph Lauren Collection gown made of Chantilly lace. The clothing brand holds a strong significance for the family, after Biden's Inauguration ceremony in 2021 saw him wearing the label head-to-toe.
Naomi announced her and Neal's engagement in September 2021 on Instagram with a selfie of the pair, as she held up her hand in the shot to show off her gorgeous engagement ring.
