Paris Hilton  and her boyfriend Cy Waits threw caution to the wind and enjoyed a very public kissing session at brunch in LA yesterday. Her microphone cords didn't seem to get in the way, as the whole episode was captured by cameras for her upcoming return to reality TV.

Paris will turn the big 3-0 in just a few days on the 17th — check out which other stars are celebrating that milestone in 2011 !
