Rachel Zoe The Grove Extra Beverly Hills designs model

On Friday, Rachel Zoe was back on the grind as she appeared on Extra at The Grove in Los Angeles to talk about her new line of ladies' underwear and rings with host Maria Menounos.

While 41-year-old celebrity stylist was busy, her adorable son Skyler was with his nannies at the park and met a new playmate. When mommy's away, the son will play!
