Hull have just given Davies a new contract and the Forest man congratulated him on social media, having caught up with him on Tuesday night.
The pair, both ex-Aston Villa, exchanged messages and Davies joked that Gardner had 'ruined' his day on Tuesday.
Indeed, Nottingham Forest drew 1-1 with promotion-chasing Hull at the KC Stadium thanks to Gardner's fantastic strike.
Aston Villa fans may have been watching that strike questioning exactly why the club decided to loan the 23-year-old out...
@22Gards cheers mate, you ruined my day yesterday but was good to see you look after yourself— Curtis Davies #6 (@TheCurtisDavies) March 16, 2016
Aston Villa travel to Swansea City on Saturday evening, while Nottingham Forest face a grudge match at Derby County during Saturday's early kick-off in the Championship.
Hull, meanwhile, travel to Middlesbrough on Friday night looking to get their promotion chase back on track.
A win could move Hull back into the automatic promotion places but Boro are a point ahead of Steve Bruce's side after their draw with Forest.
