The loved up couple are often seen wearing smart and eye catching outfits on the red carpet, although yesterday (16 July) Max caught our attention for the wrong reason.
Sporting a pair of loose fitting grey trousers, that almost looked like pyjama bottoms, the curly haired model - who met Kimberly in 2011 - failed to impress at the UK Wolverine film premiere or do his glamorous girlfriend justice.
Max teamed the strange bottoms with a double breasted grey jacket and pale pink shirt - which we have to say that we are a fan of. It's just a shame his trousers weren't a bit more tailored!
Meanwhile, Kimberly looked stunning as usual in a long yellow dress, featuring a bedazzled yellow and silver bustier.
She completed her outfit with a black clutch bag and kept her blonde hair styled in tousled waves.
The former pop star has been living in the UK for some time now with her model boyfriend and recently completed a fourth series as a judge on Sky1's Got To Dance competition.
Speaking to Reveal at the BAFTAs earlier this year, Kimberly admitted that she preferred living in England to America, claiming that she feels "more at home here than anywhere else in the world".
Max also told us that when it comes to getting ready for a glitzy showbiz event, the couple rarely help each other pick what to wear.
Maybe Kimberly should have intervened with a second pair of trousers for Max on this occasion though!
