The Murder on the Dancefloor hitmaker will be updating her accounts on and every time Kardashian shares a post, and Ellis-Bextor's messages will be inspired by the reality TV regular's content.

She writes on Instagram, "Hello all. I am working with @UKTV_Press filming a show about social media and its role in celebrity and as part of the show they have given me a little light-hearted challenge to tweet/Instagram every time Kim kardashian posts. I see she has reposted today from a shoot in 2009. Here was me at the Q awards the same year... #likekimk."

After Kardashian added pictures from a wedding she attended with her husband Kanye West over the weekend (05-06Sep15), Ellis-Bextor shared a snap of herself and her husband Richard Jones at a similar event, writing, "Turns out she doesn't post all that much! Today a photo from a wedding she and her man went to so here's (Jones) and I at the wedding of fellow bandmate Kev and his lovely wife Julia. Plus we were allowed to keep our phones - haha."

Kardashian is the most popular celebrity on Instagram with 45.4 million followers, while she also boasts 35.1 million fans on Twitter.
