With news of celebrity couples splitting coming out of Hollywood on almost a daily basis, it's hard to imagine that any are able to keep their private matters out of the public spotlight.

However, some couples manage to keep their relationships secretive by not commenting on how their relationships are going. Though they may still make headlines because of their romances, they generally only make those headlines because of their secrecy.

While some chose to keep their relationships secret by rarely going public, others just refuse to comment on press reports, preferring to keep their privacy, despite rabid fan interest. Any confirmed reports from these couple generally come from journalists unearthing public records that cannot be kept secret, including marriage licenses, deeds to homes and cars and divorce papers.

Though some notoriously private couples may have still announced splits at some time or another, some of the most successful relationships in Hollywood seem to be the ones featuring the most secretive couples. Not only do these couples (who include Ryan Gosling and Eva Mendes, Ashton Kutcher and Mila Kunis and Justin Timberlake and Jessica Biel), keep their mouths shut when it comes to their relationships in the press, but they manage to keep their relationships among the rare successful ones.

So which secretive couples are perhaps getting it right by not spilling details to the press? Scroll through the photo gallery to find out.
