Miley Cyrus spent the afternoon with two of her favorite guys ... sexy fiance Liam Hemsworth and their new puppy, Toby.

The 19-year-old Can't Be Tamed cutie posted the above pic and the following, "I love being a "fiancee." Aww!

And no doubt, Liam loves been engaged to this gorgeous gal. The former Hannah Montana starlet stepped out for a shopping spree at American Apparel in LA ... flaunting her tight tummy and toned legs. Oh, and did we mention she was rockin' tiny jean shorts and no bra.


Let's just say ... Miley looks incredible from every angle!
