Kim Kardashian hit up Sephora in New York City Monday (Feb 15) to spread the word about her new “Kim Kardashian” fragrance.

She and her boyfriend, NFL champ Reggie Bush, spent Valentine’s Day (Sun. Feb 14) together in Las Vegas at Lavo, where Kim was hosting their official “love day bash.”

Kardashian hosted club Lavo’s official love day bash, where she and boyfriend Bush enjoyed some Italian food (and an oversized Oreo for dessert!) before heading upstairs to party.

“Whether you are single or with a loved one we are going to party tonight in Vegas!” Kardashian told the crowd. She was clad in a sexy YSL white minidress with, of course, a sweetheart neckline.

Afterward, she was presented with her own “Queen of Hearts” cake and a teddy bear from Bush reading, “Happy Valentine’s Day.”
