Skinny socialite Nicole Richie and Good Charlotte boyfriend Joel Madden drop some major cash at Barneys New York and Dior in Beverly Hills on Sunday.

The two lovebirds arrived in Joel’s car (BMW 745 Li) and walked in and out of the stores hand-in-hand.

The canoodling couple kissed in-store and attracted the attention of many other shoppers. Or, at least, shoppers who were kicked out of the store because of Nicole and Joel and forced to peer in through windows.

Nicole, 25, is wearing a cow print head scarf and toting around a red quilted Chanel purse (the same one that Mary-Kate Olsen loves). MK even wrote for the New York Times last month, sharing her love for the purse:

I have a large, red quilted Chanel bag that I borrowed from my sister Ashley. I wore it to an event and never gave it back. Luckily, she’s moved on to another bag, so I’m safe for now. I’m not quite sure how many bags I have, but let’s just say I have a few. When I find a bag I like, I tend to wear it to death until I become obsessed with another one. This probably happens three to five times a year. But I always come back to the Chanel. The size isn’t overwhelming, and it has enough subtle detail to keep it interesting.

I also have the smaller version in blue and in white, but the red is definitely my favorite. I don’t have a stylist — I’d rather just do my own thing and put together my own outfits. The chain-handle bag is the perfect accent to almost any combination I come up with. I look at everything with a designer’s eye, but I wouldn’t change a thing about this bag. I think that’s why it’s a true classic.

Lindsay Lohan does make dreams come true!

Dressed in all-black polka dots, Lindsay drops a pretty penny at Barneys in New York City on Saturday night.

For one young fan boy who spotted the dream teen queen outside of the upscale department store, it was a dream come true.

As Lindsay finished her shopping and walked out of Barneys, a young boy approached her. He told her that his favorite movie of all-time was 2005’s Herbie Fully Loaded, where Lindsay plays street racer Maggie Peyton.

Lindsay blushed, naturally, and giggled her way through the rest of their conversation. Before jetting off to her lux hotel, Lindsay shook her boy admirer’s hand and thanked him for all the compliments.

Mean girl Lindsay is not!

Gwen Stefani and hubby Gavin Rossdale take their 9-month-old son Kingston on a brief shopping trip to Barneys on Wendesday afternoon in Beverly Hills.

Kingston is such a cutie in his full-on Adidas track suit!

Gwen Stefani’s “The Sweet Escape” feat. Akon moved up to third from fourth on the Billboard Hot 100.
