Sara Underwood’s Instagram Has Been Straight Fire Lately [PHOTOS]

If you only follow one person on Instagram -- make it Sara Underwood.

Former Playboy Playmate Sara Jean Underwood first caught our attention on G4's criminally underrated 'Attack of the Show.' She did regular features for the show and often filled in as co-host until the show met its demise in 2013 as the network prepared to re-brand as Esquire TV.

These days, if you ever need to find Sara -- all you need to do is hit up her Instagram and witness the smoke show already in progress. We were drawn in by her latest topless pic, in which she's holding an Ultimate Warrior wrestling buddy (seen above), and ended up scrolling through her feed for about 15 minutes. Homegirl knows how to work a camera, and it's nice to know she's keeping her nerd street cred alive post-G4. Don't ever change, SJU... well, do change, but keep taking pics of it.
