She is frequently glimpsed out and about in her hometown of New York City.

But when Nicky Hilton got pap-snapped this Tuesday, she was clear across the country in swanky Beverly Hills.

The Rothschild-by-marriage, 34, played up her enviably slender legs in a pair of skintight dark jeans as she enjoyed a stroll with her mother Kathy.

Modeling butterfly sunglasses, she kept cozy in a hoodie that was fit to set onlookers' heads turning as they asked: 'Is that Supreme?'

Kathy, who was a little-known actress before retiring the year she married into the Hilton family, wrapped up in a lacy nude scarf and sleeveless white knit cardigan.

The 59-year-old half-sister of Kyle and Kim Richards wore a black sweater with its sleeves rolled to the elbow, plus matching leggings and a bulging black bag.

Shielding her face from the California rays with a pair of shades, she accessorized with a couple of beaded bracelets and pulled on some thick olive green boots.

Kathy, a longtime pal of the late Michael Jackson, married Rick Hilton in 1979 and remains his wife 39 years and four children later.

Over the weekend, Nicky posted an Instagram photo of herself with toddler twins Emma and Mila, whose mother Katie relentlessly propelled them to online fame.

Katie Stauffer has spun this enterprise into an Instagram following that is now pushing 4 million - nearly three times Nicky's follower count.

Nicky - whose big sister is socialite, businesswoman and sex tape icon Paris Hilton - is married to James Rothschild, grandson of the 3rd Baron Rothschild.

James and Nicky got hitched at the Orangery at Kensington Palace, the London home of William and Kate, Duke and Duchess of Cambridge.

Nottingham Cottage, which is in the grounds of Kensington Palace, happens to be where Meghan Markle and William's brother Prince Harry will live as man and wife.

Before getting hitched in Valentino to James, Nicky married her old pal Todd Meister in Las Vegas in 2004, then had the union annulled before the year was out.

In 2016, Nicky and James welcomed their firstborn daughter, who fittingly for her posh parentage is called Lily Grace Victoria Rothschild.

Teddy Rothschild was born on December 20 this past year.

Paris is currently engaged to the strikingly square-jawed actor Chris Zylka, and Nicky's theory is that Lily Grace is going to be in the wedding.

The mother of two told People this month: 'I think Lily-Grace definitely will be [a flower girl]. I don’t think Teddy will be walking yet.'
