DALLAS, Jan 25, 2011/ FW/ — I hope that everyone is keeping warm this week. With temperatures dropping all over the country, it’s good to make sure that we have our warmest coats or jackets on.

Meanwhile, let’s look at what the celebrities have been up to.

Actress Mariska Hargitay celebrated her birthday over the weekend wearing an AZIAM Wife Lover made exclusively for the Joyful Heart Foundation, Harigtay’s non-profit organization aiding victims of sexual assault.

Debra Messing and Jennifer Love Hewitt were also in attendance wearing the tank. The Wife Lover tank is available for $40 at www.AZIAM.com. Ten percent of the proceeds are donated directly to the Joyful Heart Foundation.

In other parts of the country, it seems that MCM is everywhere! Seen holding MCM totes and bags are Katy Perry, Olivia Wilde and Mariah Carey.
