Then you're going to LIVE for this video!!!
She's gone undercover -- and she OWNS it!
Ch-ch-check out the video for Birthday here (above)!
What's wrong, Miles??!
Miley Cyrus wasn't so smiley when she was spotted with her HUGE engagement rock picking up some frozen yogurt at Menchie's (see below) and shopping at Target yesterday in Studio City.
Nothing like a brain freeze to get her mind off those wedding woes!
But seriously, who knew she ran her own errands?! That gurl is so down to earth, even if she doesn't look like she's enjoying it very much.
Though she's vowed not to tweet about her private life, we're happy the paparazzi are there to snap those candid moments!
We don't know what we'd do without our daily dose of Mileybird!
