Happy Birthday, Abbie Cornish and Samantha Ronson!

Two quasi celebrities - that are best known for who they are dating - celebrate birthdays today.

First, we'd like to wish a happy 26th to Aussie actress Abbie Cornish.

The birthday girl is rumored to have had an affair with Ryan Phillippe while he was still married to Reese Witherspoon. Whether or not that's true - and it is - this acting duo is definitely a couple now.

Moving on, Samantha Ronson turns 31 today. We know what this DJ will be getting as a present:

Lindsay Lohan nude. We just hope Samantha takes a long, hot shower afterwars. For like four or five days.
