As the pair reached the end of the red carpet after disembarking the plane they went in for a kiss.
According to author and body language expert Judi James, it is rare to see any form of public displays of affection (PDA) from the Trumps, and this ‘Guppy Kiss’ is a first.
So what does it tell us?
Judi explained: “Well that Melania has a sense of humour and that she might secretly be the powerhouse in this relationship after all.Related articles

It is rare to see any form of public displays of affection (PDA) from the Trumps, and this ‘Guppy Kiss’ is a first.
“The Guppy Kiss is named after the behaviour of nibbling fish who will touch lips while their bodies are kept apart.
“Celebrity couples tend to adore this form of kissing for camera as the over-pout and leaning in ritual creates a kiss that looks cute and affectionate but without any of the signals of sexuality that might embarrass an audience.”
While the mutually-affectionate Guppy should involve marching amounts of pout-and-lean, this PDA looks very much like Melania’s sole creation, says Judi.
“Her splayed feet and upward-curled lip pout suggest both humour and that she's the one pulling her husband in for the smacker, and her tight hand clasp endorses that idea.
“This clasp looks less about affection and more about control as she holds Donald's hand by the fingers and uses it to pull him in towards her to accept the kiss.”
