Tamra Barney Plastic Surgery 2014: 'RHOC' Star Debuts New Face On 'WWHL?'

Tamra Barney looked noticeably different on last night's Watch What Happens Live.

While appearing on the show to promote the currently airing season of The Real Housewives of Orange County, Barney was bombarded with questions about possible work on her face, both from host Andy Cohen and from the audience.

"Have you done something to your face?" Cohen asked the 46-year-old, whose face appeared tighter and lips looked fuller, according to a July 15 report by TooFab. "I feel like I'm looking at something, some fillers?"

In the past, Barney has copped to a handful of procedures, including breast implants, which fans saw her remove on The Real Housewives of Orange County, and Botox. However, last night, Barney wasn't ready to admit to much of anything, although she did say she "maybe" had "a little bit" of work done to her face.

On Twitter, fans were just as curious about what Barney may have done.

"What is wrong with @TamraBarney's face?! She can't even move her top lip! #BotoxMuch," one Twitter user wrote during the show's airing. "Can't tell if @TamraBarney is mad or if she just can't move her face," added another.

Barney also caused a stir on Watch What Happens Live with her digs at on-again, off-again best friend, Vicki Gunvalson. When Cohen asked about the relationship, Barney didn't hold back, telling him that this season, Gunvalson is an "a** kisser."
