Britney Spears is stronger than yesterday, thanks to the support of her son.

Close to a month after being arrested on a charge of driving under the influence, Britney reunited with her younger son Jayden Federline, marking her first post on social media since the March 4 incident. 

In a video shared to her Instagram on March 27, the “Toxic” singer posed in the mirror with her 19-year-old as they took turns holding a red phone to snap pics.

Britney—who was wearing low-rise white shorts and a long-sleeved cropped white top—was clearly happy to have her son by her side as she tossed her hair and smiled for the camera.

At one point, the 44-year-old—who also shares son Sean Federline, 20, with ex-husband Kevin Federline—playfully danced around Jayden and pretended to hump him, though she quickly stopped and acknowledged the move was “stupid.”

“Naughty little sister and a mama too!” Britney said while leaping around her son. “Composure, I’m being very composed.”
