All the tongue-wagging that occurred after exes Cameron Diaz and Justin Timberlake greeted each other with a kiss at the premiere of "Shrek the Third" this week was no biggie, the actress told Meredith Vieira on the "Today" show Wednesday.
"Look, we're friends so it's OK," Diaz said. "It's not something that you really worry about. I think all you want is for the person that you care about to be happy. And I think we both are, so it's easy for us to see each other. And it's easy for us to greet each other."
Diaz said living under the microscope is a flashback to the days of high school.
"Even underneath the microscope of the world, it's not really that difficult, you know, because there's nothing big about it, it's no big deal," she said. "It's like high school isn't it? We as celebrities are sort of like popular kids and everybody wants to know our business, so people make a big deal out of it but it's not really a big deal at all."

2Timberlake and Diaz split in January amid reports of relationship troubles.
They issued a joint statement at the time that said they had ended their romantic relationship. The statement said they "have done so mutually and as friends, with continued love and respect for one another."
The couple began dating in 2003. Since their split rumors have circulated that Timberlake has had flings with Jessica Biel and Scarlett Johannson. Diaz has reportedly spent time with surfer Kelly Slater and actor Djimon Hounsou.
