I completely disagree. Every aspect of their life has been thrown in our faces, including when Tom cheated or whatever you want to call it.
Had they kept their private lives private, we wouldn't know anything about them except for their careers. They chose the other route and can't now turn around and complain that we shouldn't be involved or paying attention or whatever you want to call it.
And please do not equate non-celebrities with guys like Tom and Lance, about us rooting around every corner of someone's house whom the public doesn't know. Coming from someone who lives in the UK, a country known for paparazzi to root around every corner of everyone's home, it's disingenuous.
