Erin posted the following on her twitter account about her Nip/Tuck upcoming episode:

My Nip/Tuck episode airs Dec 9. Me, Dr. Christian Troy, an office desk and a pair of thigh-high stockings. Yum...

I loved working on Nip/Tuck! Julian McMahon was wonderful - so nice, so professional. A lovely human being!
