Does Silver the hedgehog have a girlfriend

Some Sonic fans (myself included) support the pairing of Silver the Hedgehog and Blaze the Cat (Silvaze for short). However, any Silvaze is fanart and is not officiated by SEGA. Other pairings with Silver are less common, but are certainly out there, such as Silver and Amy Rose (Silvamy).

Bottom line: Not officially, but Blaze is the most common among fans.
