The Johnson family from TLC's '7 Little Johnstons'

On Season 14 of 7 Little Johnstons, TLC viewers have watched Amber and Trent Johnston's kids experience major milestones. Their youngest children, Emma and Alex, recently attended their junior prom on the show—but in real-time, the siblings just went to their senior prom.

Amber took to Instagram on Saturday, April 20, with a carousel of photos of her kids and their friends all dressed up for the high school dance. "• SeNiOr Prom •," the doting mom captioned the update.

In the pictures, Emma rocked a strapless aqua-blue gown while posing with her date, who wore a matching blue tie. Alex looked dapper in his suit with a green tie, seemingly opting to enjoy the company of his friends, twin brothers Ryan and Sean.

Other shots showed Emma getting her hair done for prom. Her older sister, Liz, also helped her with her makeup for the event.

In the comments, fans react to Emma and Alex's prom photos. One Instagram user wrote, "Absolutely stunning, Emma! That dress looks perfect on you," while another commented, "Miss. Emma, You look beautiful, and your date is quite handsome as is Alex, and the rest of the Guys."

Another fan wondered, "New boyfriend?"

Still, others were curious about what happened to Alex's Season 14 girlfriend, Allie, who was his date for his junior prom.

One person commented, "Where’s Alex’s girlfriend??" while another pointed out, "Awe no Allie?"

It's unclear whether Allie and Alex parted ways or if she couldn't make it to prom this year.
