'7 Little Johnstons' Star Alex Gives His Prom Date the Sweetest Homemade Accessory (Exclusive Clip)

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

Prom is just around the corner, and the two youngest 7 Little Johnstons stars recently showed off their outfits, dates and special mocktails named after their cars to celebrate.

On Tuesday, April 2, fans will see Amber and Trent's kids, Alex and Emma, prepare for their junior prom. TLC shared an exclusive clip of the upcoming episode with Parade—and Alex's sweet gift to his girlfriend, Allie, will leave viewers swooning.

The clip begins with Emma, Allie and Emma's "date"—her cousin Ella—walking into the room to reveal their gorgeous dresses.

"I think we all look pretty great," Emma tells producers before joking, "We're just ready to be on the dance floor to show our moves to everyone else. I'm just kidding."

After the girls debuted their dresses, Trent got to work whipping up mocktails inspired by the vehicles the teens drive. There was a Golden Cavalier, Ranger Maverick, Seasoned Corolla, Fizzy EcoSport and Accord Royal.

The sweetest moment by far in the sneak peek was when Alex made his way downstairs. While looking rather dapper, he approached his girlfriend. "So I made this for you, Allie," he said. "It's an origami corsage if you want to put it on."

Alex then secured his homemade gift, which featured blue flowers, to Allie's wrist.

"When I saw Allie all ready for prom, I thought she looked super beautiful," Alex told producers with Allie beaming by his side. "And it was definitely worth the wait for me to see her dress."
