Vienna Girardi isn't letting her breakup with Jake Pavelka ruin her summer.

Less than three weeks after she announced she was dating John Sala, the 24-year-old reality star debuted a bold new bob at a party in Hollywood Wednesday night.

"Getting my makeup done by @florid0 and my new look @ninezeroone can't wait to show you all a picture," Girardi tweeted earlier that day. "Hint: no more extensions!"

Already a fan? Girardi's pal Amber Lancaster, who currently stars on MTV's The Hard Times of RJ Berger.

"Me and my girl @ViennaGirardi with her beautiful new 'do!!! Love it!! Props to @ninezeroone," Lancaster, 29, tweeted Wednesday.
