Break out the cake and balloons, because a celebration is in order for Michelle Obama’s birthday. On Jan. 17, the former first lady turned 57. Naturally, our former President Barack Obama wrote a beautiful message to commemorate the occasion. We wouldn’t expect anything less from these two. “Happy birthday to my love, my partner, and my best friend,” Barack captioned his Instagram post. “Every moment with you is a blessing. Love you, Miche.” How sweet! After 28 years of marriage, Barack and Michelle have certainly spent many special birthdays together, but we hope this is the best one yet.
