(Cover) - EN Showbiz - Rachel Zoe is "happy all the time" now she is a mother.

The celebrity stylist and star of television show Rachel Zoe Project gave birth to her first child Skyler Morrison in March of this year.

Since then, Rachel has relished her new role.

"I'm happy all the time now," she told People magazine. "I swear to God, I walk around with this smile on my face all day. It surprises me."

The 39-year-old was initially afraid of dealing with the daily demands of motherhood on top of her busy work schedule. However Rachel, who is married to Rodger Berman, says she is finding being a mom less difficult than she imagined.

"[I thought I'd be] exhausted and stressed trying to balance everything [but son Skyler] has just made it easier in a way," she confessed.

When she does feel pressure, Rachel looks to her friend and fellow fashion mogul Stella McCartney for inspiration.

The stylish star is humbled when she looks at other successful working mothers.

"Once you have a baby, your time becomes way more efficient and focused," she said. "If [Stella McCartney] can do it with four kids and run the business she's running, I think I can do it [with one]."

Although she loves Skyler unconditionally, Rachel is hesitant about whether or not she wants to have more children. The fashionista says she is looking forward to the foreseeable future with her newborn for now.

"I don't know about more kids," she says. "I want to enjoy Skyler for now, so we'll see. Maybe." (C) Cover Media
