Jennifer Garner, 49, gave us teenager vibes with her latest fun-loving video! The actress looked young and energetic while happily roller skating in an indoor rink in the Instagram clip, which was shared on May 28, and even took a moment to show off a special skill while going full speed. At one point, she bent down and stretched one leg in front of her while holding onto her ankle with one hand and stretching out her other arm in the opposite direction as she kept incredible balance.
