She's growing up so fast! Beyonce posted more pictures to her Tumblr on Friday, Aug. 1, including one of her 2-year-old daughter, Blue Ivy, wearing high heels.

The picture showed the fashionable music scion walking through the aisles of a spacious private plane in a white eyelet frock, black studded belt, and pink plastic heels. It appeared as if Blue was cautiously making her way through the aircraft, with one hand placed on the arm of a luxurious leather seat.

Blue Ivy's fabulous jetsetting lifestyle has been part of her mom's global On the Run tour with husband Jay Z. Exhausted from traveling, Blue was pictured in another snap fast asleep in Beyonce's arms.

The singer has been playfully teasing family snaps on her Instagram amidst speculation about her marriage. Beyonce even posted a picture Thursday, July 31, of a fresh manicure featuring nail art which read, "J + B." Her left fingers were painted with gold "OTR" letters.

Another pic shared by Bey features her hip hop mogul hubby holding their daughter on a dock as the two gaze across a bay.

The power couple has four more tour dates in the U.S. before a one-month hiatus. They will then finish off their final two shows in Paris, France, on Sept. 12 and 13.
