Kim Kardashian is considering designing her next fragrance with her boyfriend.

The socialite launched her self-titled perfume this week, but is already planning a new fragrance, which she said she may co-design with American Football player Reggie Bush.

Kim, 29, said: "Reggie and I have talked about doing a fragrance together - something that is kind of unisex."

However, when asked which of her scents Reggie prefers, Kim said: "He just likes my natural sexiness. He likes my natural scent."

For the fragrance launch, Kim wore a black PVC dress, a look she reprised later in the week when she donned a black PVC corset over a grey dress to launch a collection designed by her and her sisters Kourtney and Khloe for fashion chain bebe.

The range, which is available this month in bebe stores in the U.S, consists of basic jerseys, fitted blazers and leather separates.

She tweeted: "Heading to the bebe show! Can't wait for u guys to see this hoodie dress w/ leather corset I have on! Dope! (sic)"
