The reality TV pair have sparked rumours that they are in a relationship after spending a great deal of time together since Stephanie landed in the UK last month.
Stephanie, who starred in US show The Hills, has even been introduced to Spencer's Made In Chelsea cast mates!
But although love is clearly in the air, the twosome have been temporarily torn apart this week by their differing schedules and Stephanie has headed to Glasgow, leaving Spencer pining for her back in London.
Yesterday (3 July), Spencer tweeted a candid photo of himself and Stephanie looking cosy on a night out, along with the caption: "Miss the Pratt... @stephaniepratt."
Stephanie then replied with a picture taken on the same night, although this time the rumoured couple are kissing! She wrote alongside the snap: "Miss u too babe @SpencerGeorgeM."
Could this be confirmation that the controversial stars are indeed an official item?
Well, if Stephanie is getting serious with Spencer, she's already got her sister-in-law Heidi Montag's approval.
Earlier this week, the busty blonde tweeted: "@SpencerGeorgeM @stephaniepratt cutest couple ever! We will have Christmas in Colorado this year! Xo."
Heidi and her hubby, Stephanie's brother Spencer Pratt, struck up a friendship with the notorious Chelsea ladies' man after flying to the UK for their appearance on Celebrity Big Brother in January.
Spencer Matthews has even admitted to aspiring to be like Spencer Pratt, as they both have been depicted as villains on television.
But this villainous nature and bad reputation clearly hasn't put Stephanie off!
Despite Spencer confessing to bedding another woman while dating co-star Lucy Watson last month, Stephanie doesn't seem to mind and even appeared to make a joke about his infidelity on Sunday evening (30 June).
She tweeted: "DON'T CHEAT ON ME TONIGHT! @SpencerGeorgeM IM SERIOUS!"
After putting up with her brother for a number of years, Stephanie obviously knows how to deal with troublesome Spencers, so maybe she'll be the one to put this Spencer in his place!
