George W. Bush, the 43rd president of the United States, has shown a different side of himself to the world since he left the White House.

For starters, he's a modern-day grandfather, showing off the newest member of the Bush clan- not with an accordion of photos from his wallet - but rather on Instagram.

The caption, which reads, "Happy #GrandparentsDay," shows that even though Bush, who recently had heart surgey, has only been a member of the social media site for a month, he has already mastered the art of the hashtag.

The eight photos posted on the account, which so far has over 27,000 followers, display a mix of both public appearances and behind-the-scenes snapshots.

"Say hi to Bob, a stray who wandered onto the ranch in Crawford. Now he lives with Miss Beazley in Dallas."

In addition to his Instagramming hobby, Bush told ABC News' Diane Sawyer in April that he now paints daily, and works with what he called a "patient" instructor once a week at his Dallas home. "I love to paint. It is - painting has changed my life in an unbelievably positive way," the former president said.

Bush joins a slew of politicians already on Instagram, including Speaker John Boehner and President Obama, though he has yet to embrace their love of filters.

Several of the photos posted on the former president's account hint at his love for the game of golf.
