Major congratulations are in order for Dylan Sprouse and his longtime girlfriend Dayna Frazer: the couple's four-legged bundle of joy has hit a major milestone. Their beloved pet dog Magnus turned one-year-old and of course Dylan took to Instagram to share the most adorable pic ever of the precious pooch on his big day.

"Magnus turned one!" Dylan wrote in the caption of the glamour shot he posted of his dog, who was in the most festive spirit sporting a legit party hat. And yes, that is uncle Cole you see how gave the pic a double-tap because it is ridiculously adorable.

Seriously, this little English bulldog is hands down one of the cutest you will ever see. He's had a rather exciting first year of life with his parents, having his own Instagram account that currently has more than 56,000 followers. Casual. Dylan and Dayna adopted little Magnus back in August of 2016, in honor of Dylan's 24th birthday, so he obviously means so much to the pair. Plus, he's gotten rather close with Cole too.
