The mother and daughter were spotted walking through the arrivals hall this morning (11 October) along with Kelly's fiancè Matthew Mosshart.
Kelly was dressed in a monochrome coat and was wearing her hair in an up 'do with a scarf, topping off her look with statement sunnies.
Linking arms with her mum Sharon, the ladies appeared to be deep in conversation as Matthew followed on behind.
Earlier this week, Sharon told Daybreak viewers that she wanted Kelly to be in the UK to support her return to The X Factor live shows.
On Monday (7 October), Sharon - who is mentoring the Overs category - said: "She's a naughty girl because she's not here!
"She wants to come in for the first show and is hoping to be here for the first show to cheer us on."
We're glad to see Kelly didn't let her mum down!
