Show bosses confirmed the judging line-up today as they announced the audition process for the new fifth series.
'Everybody In Love' singer Aston, who is currently in Los Angeles working on music, joined the panel on the dancing competition last year to replace tap dancer extraordinaire, Adam Garcia.
Despite Aston's departure, former Pussycat Doll Kimberly Wyatt and Diversity star Ashley Banjo will still be returning for the new series. A third judge is expected to be announced at a later date.
Sky's head of entertainment, Phil Edgar Jones, said: "We really enjoyed working with Aston - who brought energy and vibrancy to his role as judge and we are excited to see who will step into his shoes."
In December, Aston, along with bandmates Marvin Humes, Oritsé Williams and JB Gill, bowed out of JLS after six years together following a 'Goodbye' farewell tour and album.
Speaking about how Aston fitted in as a new judge on the show, Ashely told Reveal at the start of series four last year: "It's a big ask coming in for the fourth series, into a journey if you like, and putting your stamp on it but Aston's done really good.
"He brings a completely different perspective with his experience in these kind of shows, and also his experience as a performer and an international artist. Me and Kimberly come at it from a dancer's point of view, and so does he, but he's still got that pop star perspective as well which is really interesting."
The fifth series of Got To Dance, which is expected to air on Sky1 in the Summer, will culminate with a week of semi-final performances in front of a six-thousand strong crowd.
Davina McCall, who will return as the host, said: "The joy of dance is completely infectious and I was bitten by that bug long ago. Each year I learn something new. Last year it was krumping - whatever next?!
"I couldn't be happier to be returning to Got To Dance and I can't wait to meet more dancers ready to take on the challenge. Lets get to twerk... I mean work!"
