A baseball cap on Eminem's official webstore has suggested that the rapper could be set to release a new album next year.

Eagle-eyed fans noticed that a new cap posted on his online shop, called Eminem Baseball Tribute Champ Hat, lists the dates of his solo album releases.

The item's listing says: "Side panel is dedicated to the landmark Eminem solo albums."

The dates on the cap are 1996, 1999, 2000, 2002, 2004, 2009, 2010 and 2013.

Eminem's last studio record, 'Recovery', was indeed released in June 2010.

The cap, meanwhile, will see some of its proceeds go towards the Marshall Mathers Foundation, which is focused on youths.
