The Canadian superstar - and her ‘Sum 41′ star husband Deryck Whibley were spotted shopping at exclusive baby boutique Petit Tresor in Los Angeles on Monday, as well as the exclusive Kitson for Kids and Lisa Kline Kids outlets.

During their spree in Petit Tresor, the couple, Avril, 23, and Deryck, 27, reportedly purchased a cheetah diaper bag, baby AC/DC T-shirts and a pacifier holder.

The ‘Complicated’ star also appeared to be shielding a possible baby bump by hiding her stomach with a large bag, according to American photo agency x17.

Avril recently denied rumors she was expecting, insisting people are always making up stories about her.

She said: “Remember in high school when people would start fake rumors about you? Well, this isn’t high school - it’s like the entire world.”

Avril began dating Deryck in 2004 and got engaged a year later after he proposed during a romantic trip to Venice, Italy. They married on July 15 2006 at a private ceremony in California.
