Locke - known for his Union Flag car and jacket and his penchant for fake tan - left "Made in Chelsea" after five series so that he could appear on "Celebrity Big Brother" in January 2014, reported Digital Spy.
"I am delighted to be returning to a show that I am so proud of being involved in from day one," Locke said.
"I can't wait to be back on the Kings Road adding some more love, laughs and just a bit of the ridiculous!"
Locke's not the only cast member returning to the Chelsea franchise, as his ex-girlfriend Gabriella Ellis - who now lives in LA - will arrive on "Made in Chelsea: LA" next week.
