Cheryl Tweedy is returning to "The X Factor" after two years.
The 34-year-old singer first joined as a judge on the talent competition in 2008, and after leaving the programme in 2015 the brunette beauty is set to make her big comeback as a special guest during the Judges Houses round where she will assist Simon Cowell in his decision making process.
However, the "Fight For This Love" hitmaker - who has six-month-old son Bear with her partner Liam Payne - reportedly felt some tension during the meeting and curtsied to the 57-year-old music mogul to "break the ice" when they boarded a plane to Nice, in France.
Speaking about their reunion to The Sun Online, a source said:
"She curtsied for him when she first got onto the plane - it was her way of breaking the ice."
However, the Girls Aloud band member and Simon - who has three-year-old son Eric with his partner Lauren Silverman - swiftly picked up where they left off as they "bonded" over parenting.
The insider continued: "Simon and Cheryl bonded over parenting during a private jet and helicopter flight to the house."
Although the pair have not worked with one another for a while, they still share a "very close" bond.
The source added: "Despite the break they've had from each other, they're still clearly very close."
While Cheryl joins Simon in France to select what groups he wants to take through to the next stage, 24-year-old grime artist Stormzy - whose real name is Michael Ebenazer Kwadjo Omari Owuo, Jr - will accompany judge Nicole Scherzinger in South Africa to whittle down the Overs, and Sharon Osbourne has enlisted the help of her daughter Kelly and son Jack to select three contestants from her Girls category to take through to the live show.
