'This is Mrs. Barker, how may I help you?' Kourtney Kardashian embraces her new last name

Kourtney Kardashian put on a busty display in a series of sultry photos posted to her Instagram on Saturday.

The Kardashians reality TV star, 43, looked sublime in a black blazer worn over a black lace bra that showed off her ample cleavage, and a mini skirt that highlighted her toned legs.

The recently-married beauty pretended to take a call in the snaps, as she embraced her new last name, writing, "Hi yes this is Mrs. Barker, how may I help you?" to which her husband, Travis Barker, 46, playfully responded: "I got a few ideas."

Kourtney paired the sexy look with black sandal heels that showed off her red pedicure and was seen standing in the middle of a spacious bathroom. 

She further accessorized the all-black look with a black heart-shaped purse that was embellished with rhinestones. The Poosh founder wore her long black tresses in a sleek bun, with one strand left cascading down her cheek.
