Checkmate! Pregnant Nicky Hilton covers up her blossoming bump in chic tweed coat and cosy navy jumper as she steps out in Manhattan

She is expecting her second child with her husband James Rothschild.

And Nicky Hilton sported a glowing complexion on Sunday as she strolled down Madison Avenue in New York.

The 34-year-old wrapped up warm for the weekend outing, covering her barely perceptible bump in a stylish red and black tweed coat.

Nicky, who is the younger sister of the reality TV star Paris Hilton, paired her coat with a cropped navy jumper and crisp white shirt for the chilly outing.

Just a glimpse of her bump was evident underneath her soft brown cashmere scarf, as she stepped out alone. 

The mother-of-one showcased her enviable pins with tight indigo jeans and complemented her ensemble with a pair of suede Gucci loafers and a jet black bag.

Her long blonde tresses were swept off her face with a chic pair of sunglasses.

Just last week, the heiress was glimpsed out in the Big Apple, pushing her and James' one-year-old firstborn Lily in a stroller.

Steering the stroller across the cobblestones in NoHo, Nicky draped her bump in a sky blue button-up blouse.

She left a couple of the top buttons undone, allowing for a view at the glinting necklaces she had strung on for her outing.

The expectant mother married the grandson of the 3rd Baron Rothschild last at the Orangery in Kensington Palace Gardens.

Last July, she gave birth to the couple's first child, a daughter who in a nod to her posh parentage has the full name Lily Grace Victoria Rothschild.

Citing a representative for Nicky, People reported her current pregnancy this July.
