Holly Montag stayed mum on buddy Stephanie Pratt's Sunday DUI arrest when RadarOnline.com caught up with her at Monday night’s launch party for ESPN magazine's body issue in Los Angeles, California.
When asked about her fashion selection for the occasion, Holly said: "This is... I don't know what -- a leather jacket."
She said she had a "wonderful" birthday (which her and Pratt were celebrating prior to Pratt's arrest).
Holly, who turned 26 on Oct. 15, is the sister of The Hills' Heidi Montag. In June, she joined the cast of NBC’s I'm A Celebrity...Get Me Out Of Here after her sister and brother-in-law, Spencer Pratt, left the reality show after a series of fiascoes.
