The notorious ladies' man is often seen on Made In Chelsea kitted out in big coats and thick jumpers, but yesterday (30 October) he showed off his new trim physique in a fitted blue ensemble.
And dare we say it, we think he looks great!
Spencer wore a dark blue jacket with a navy blue sweatshirt underneath and a bright blue pocket square to offset the darker shades.
He also donned a pair of dark denim jeans, slicked his hair into a slight quiff and opted for the clean shaven look, as opposed to the stubble he is sometimes seen with on the popular E4 show.
Very smart indeed!
Unusually, Spencer arrived at the pop-up club party (which was held in celebration of Westfield shopping centre turning five years old) on his own and without a date on his arm.
The Chelsea lothario is frequently seen on red carpets and at events in the capital with a pretty girl by his side, but it looks he decided to have some female-free fun yesterday.
Or perhaps his date let him down last minute?!
Spencer is currently causing a stir (again) on the new series of MIC by trying to rekindle a friendship with ex-girlfriend Louise Thompson and also dating American reality TV star, Stephanie Pratt.
However, he and Stephanie decided to go their separate ways after the summer months were over and Spencer has since admitted that he merely considered the Californian blonde a "holiday romance". Ouch!
