This family won't soon forget this presidential cameo.

As former President Barack Obama set off on a morning stroll among the cherry blossom trees on the bank of the Tidal Basin in Washington D.C., he happened to walk by Portia Moore kids Preston, 4, and Belle, 20 months, as they posed for a photo shoot. The Virginia mom didn't notice Obama at the time, revealing it was her husband Damien Thomas who pointed the former president out after they were finished.

"It’s the kids turn to take a photo together and Damien is saying something to me," Moore wrote on her Instagram April. 1, alongside pics of the photobombing moment. "I’m just focused on Preston not running towards the water (peak mom moment)."

The 40-year-old continued, "After that shoot was done I pick Preston up and asked Damien, 'What were you saying'? He goes, 'That was President Obama who just walked by' and looks his direction. I was like whaaaaat?!"

Moore said she ran to the photographer and asked her if she got the picture. "She scrolls through and BOOM there is it!" she wrote. "The perfect shot!"
