The couple, who split earlier this month, were all smiles as they danced together at the event.
The former Strictly Come Dancing contestant was caught kissing Katya in the street last year.
The pair's spokesperson has insisted the break-up was not a result of last year's Strictly scandal.

"We’re over it, I think everyone else is over it, let’s just move on."
They'll both back on Strictly this summer.
He also spoke for the first time about Rebecca Humphries' infamous Twitter statement.
The model and TV personality had not one but two partners in the final's ensemble number.
"If they’re both single then I think it doesn’t matter... not so much if one is married."
"Otherwise I would never have known that I am not crazy."
