Big Sean has been ''Gleekin' heavy'' over his fiancée Naya Rivera's TV show.

The rapper - whose engagement was confirmed earlier today (04.10.13) - is in awe of Naya's portrayal of lesbian cheerleader Santana Lopez on hit musical show 'Glee', and has been converted into a true 'Gleek' since falling for the Latina beauty.

He told the new issue of GQ magazine: ''Yeah, I watch ['Glee'] now, I've definitely caught up on it. I'm Gleekin' heavy. How could you not, man, if that was your girlfriend, you'd probably be Gleekin' too.

''Some of the episodes are a little much for me, but I like how they touch on real issues that people can really relate to. And people can just relate to something and confide in it. I think it serves a great purpose in society.''

Sean has been ploughing through box sets of all four seasons of the show - which also stars Lea Michele, Matthew Morrison and the late Cory Monteith - since he started dating Naya six months ago after meeting on Twitter.

And the 25-year-old hunk was clearly enjoying himself last night (03.10.13) as he tuned in for the brand new episode of 'Glee' on FOX, which saw Naya lock lips with pop princess Demi Lovato, who is guest starring as love interest Dani.

He posted an X-rated comment on Twitter as the girls shared a smooch, which led even his most loyal fans to respond with incredulous exclamations of ''oh my god''.
