She was most recently spotted taking an interest in her adopted dad's industry at a Jazz and Heritage Festival in New Orleans.

She wore her curly brown hair up in a messy bun and accessorized with a necklace, a pair of earrings and two bracelets.

Richie carried with her a reusable water bottle, a blue jacket and a large black hobo purse.

She shaded her eyes from the sun as her and Hough were seemingly deep in conversation.

Her blonde hair fell loosely around her face as she sported a pair of black sunglasses. 

The Footloose actress also carried a reusable water bottle with her to stay hydrated during the sweat sesh. 

Richie was most recently seen roaming the festival grounds at a Jazz and Heritage Festival in New Orleans, dressed for a good time in a festive yellow swimsuit.

In addition to the busty suit, the 5ft1in TV personality rocked a hippie vibe with her multi-colored parasol featuring strips of decorated fabric and a busily decorated blanket wrapped around her waist.

She also had on a pair of cut-off jean shorts, black sneakers, and a pair of large aviator sunglasses.

The Simple Life star had her hair done up in two Princess Leia-style side buns as she was seen heading to the main stage to catch Katy Perry's headlining show. 

Though it's ostensibly a jazz celebration, most of the headliners play more popular styles of music, though there are still plenty of jazz musicians on the bill.

BFFs: 'I love Nicole,' Paris said of Richie. 'We actually were just texting like three days ago because it's our high school reunion and she was reminding me of the date ... I really want to go, and I love her.' (pictured May 21 in New York City)

Also in the news: Paris Hilton recently appeared on Watch What Happens Live with Andy Cohen and spoke about her friendship with her one-time costar on The Simple Life, saying 'I love Nicole, we actually were just texting like three days ago because it's our high school reunion and she was reminding me of the date ... I really want to go, and I love her.'

Hilton was also asked about her friendship with Lindsay Lohan, and she didn't quite have anything as nice to say about her. 

After a long pause, Paris said: 'She's beyond,' then clarifying her statement: '[beyond] lame and embarrassing.' 

Hilton and Lohan, 32, were close friends in the early 2000s before they ended their friendship in 2006.
