Spencer was all smiles as he posed for photos on the red carpet on Monday evening (4 August), before going to watch Sylvester Stallone, Arnold Schwarzenegger and Wesley Snipes in the latest action movie.
Emma, who showed off her figure in a Stella McCartney dress, arrived with her brother on the red carpet, but it wasn't long before she joined Spencer and Hugo at the after party held at DSKTRT nightclub.
Of course, Spencer and Hugo are best mates, and their friendship was played out on screen until Hugo left the show after the third series in 2012.
Spencer and Emma have history too. Emma appeared in early episodes of MIC's seventh series, where she was introduced as Spencer's love interest and long-time friend.
Spencer previously admitted on the show that he was "borderline infatuated" with Emma, adding that he "really gravitates" towards her.
Things did turn sour for the pair when Emma was invited to join Spencer in Italy, not knowing three of his exes would be coming along too, but it seems to be all water under the bridge now!
At the end of what appeared to be a very good party last night, Spenny was then photographed outside the nightclub with two mystery girls. Oooh!
Meanwhile, a teaser for the first Made In Chelsea: New York episode has been unveiled and it shows singleton Spencer up to his usual tricks as he chats up a mystery brunette... despite knowing that she's already caught Stevie Johnson's eye!
Made In Chelsea: New York airs Sunday 10 August at 9pm on E4.
