Katie Holmes Makes Surprise Appearance At Murder Trial

Katie Holmes Wednesday made an unexpected cameo at a grisly murder trial in New York, and RadarOnline.com has all the details for you.

Katie, 33, was at Queens Supreme Court watching her friend, prosecutor Leigh Bishop, make an opening statement in the case of man accused of shaking to death his 2-month-old baby girl back in 2007, her rep told the NY Post.

Katie wasn't wearing any makeup in the outing, the paper reported, and left after a brief time.

The actress is coming off the Broadway production Dead Accounts, which wrapped up last week after just 27 previews and 44 performances.
