Lauren Conrad fun 28th b-day!

If anyone knows how to throw a crafty theme party, it's Lauren Conrad. So for the reality star-turned-clothing designer's 28th birthday and her fiance William Tell's 34th birthday, she threw a joint hoedown for their closest friends and family.

The engaged couple's actual birthdays are only six days apart -- hers is Feb. 1 and his is Feb. 7 -- so celebrating together was a natural fit. The party was held on Friday, Feb. 7 in the Rivera 31 cocktail lounge inside of West Hollywood's Sofitel Hotel.
An eyewitness tells Us Weekly that in the middle of the party, LC picked up the mic and sang "You Are My Sunshine" to her future hubby, and "the room filled with 'awwws' and flashing cameras." After the song, the two shared a long kiss and then continued to mingle and pose for photos with guests.

Conrad's mom Kathy and sister Breanna attended the festivities, which seemed to be mostly made up of friends and family. Former Hills costars Stephanie Pratt and Frankie Delgado were also spotted at the fete.

Befitting the country Western theme, guests wore straw cowboy hats and danced to live music from the band; they noshed on mini flatbread pizzas, cheeses, bruschetta, red velvet cupcakes, and cake.
At one point, Conrad and Tell were spotted dancing together to Darius Rucker's "Wagon Wheel," and "looked extremely in love and happy all night," the eyewitness reveals.

Conrad's guests started leaving the event around 1 a.m., as the hostess hugged and thanked her friends.
Two close pals who couldn't make it? Conrad's rescue pups Fitz and Chloe. The best-selling author posted a picture of her pets dressed for the party on Instagram, captioning, "Trying to figure out how to tell these 2 they aren't coming to the birthday hoedown…"
