Do cell phones have more important uses than functioning as a mirror? Well, we don't know of a better use for a phone  and a certain reality star appears to agree!

Former Real Housewives of Atlanta star Kim Zolciak posted a photo to Instagram on December 7 of herself on what appears to be the set of TV show. Kim is holding up her phone in the shot and seems to be admiring herself.

"Lol my phone has soooo many uses!!! #mirror," she captions the pic. Too funny!

We love that Kim is willing to post slightly embarrassing pics of herself and admits when she is giving herself a once-over. Nothing wrong with a little vanity once in a while, right? 

But even more interesting about this photo is the fact that it appears to have been taken on the set of her reality show, Don't Be Tardy....

Season 2 of Kim's show aired its last episode in June 2013, but quite a bit has happened in Kim's life since then. For starters, she has given birth to two beautiful twin babies, Kane Ren and Kaia Rose. So we have our fingers crossed that Season 3 is currently filming!

Do you think Kim is now filming her show?
