The Americans (bless ‘em) have a great expression for a certain type of person – Media Whore

Wictionary, the online dictionary, defines it as:

A person who craves media attention; someone who will apparently do anything to remain in the media spotlight.

Do you know anyone like that?

John Mann, the self-appointed, self-serving, self-righteous scourge of the expenses claimants who made allegations of wrongdoing by Alan Duncan, today got criticised by the Commons Standards and Priveleges Committee  for his lack of courtesy in going to the media before Mr Duncan or the Commissioner with his complaint. The Committee found that Mr Duncan had acted entirely within the rules and Mann’s allegations were unfounded.

Running his mouth off to the press is a favoured pastime of John Mann, earning him the sobriquet of Rent-a-Quote. The fact that his comments are often without foundation bothers him not a jot as long as he can see his name in print or his smirking face on the telly.
