Harry H Corbett and Wilfrid Brambell (if you believe that recent Doco, Brambell was also a closet Gay apparently)
Sid James and Kenneth Williams (comes from Williams diaries, so this is true)
Edit
Beaten to it.
Corbett and Brambell did get on, they just didn't socialise together outside work (in much the same way Morecambe and Wise led separate lives but were good friends)
Brambell wasn't really in the closet (on more than one occasion BBC producers were despatched to get him from the gents' toilets on Shepherds Bush Green)
Comments
Noel & Liam Gallacher.
Cheryl Cole and Charlotte Church
The most recent one was supposed to Gwyneth Paltrow and Madonna, until they were seen a few days later having dinner together!
But I imagine Kanye West and Taylor Swift aren't exactly best friends?
What's the issue between them?
Jimmy Bolam and Rodney Bewes (The Likely Lads)
Mike and Bernie Winters
Maggie O'Neill and virtually everyone on EastEnders
Mariah and Jennifer Lopez
Christina Aguilera and Mary J Blige
Christina Aguilera and many other celebrities who have complained about her attitude!
Steptoe and Son are another oldie.
Same era, sadly no longer with us, but:
