Heidi Montag is back in her bikini!
The former star of "The Hills" just turned 27 on Sunday (or at least parts of her did) and celebrated by staging a photo shoot in a glittery, gold two-piece.
Never missing an excuse to show off the results of her plastic surgery overhaul, Montag struck a couple provocative poses by the pool.
While Heidi and her husband Spencer Pratt have kept a relatively low profile lately, they have a secret project in the works.
No word on what they've got up their sleeves, but she's been tweeting about it non-stop over the past few days.
So glad @spencerpratt convinced me to be part of the new project! Getting such a great response!! Yay!— Heidi Montag (@heidimontag) September 20, 2013
Forgot how exhausting these productions can be. Seeking INNER beauty rest & recovery.— Heidi Montag (@heidimontag) September 17, 2013
Today was prep for new proj. @spencerpratt & I are in -- I can't really describe it but it's going to be WILD!— Heidi Montag (@heidimontag) September 8, 2013
The 27-year-old has come a long way from when we first saw her on "Laguna Beach" and "The Hills" hasn't she?
Check out how much Heidi and her for MTV costars have changed since appearing on the show in the gallery above!
