While in Paris to promote her Spring 2010 Winter Kate Collection, Nicole Richie took time out to sightsee with 5-month-old son Sparrow.
Alongside a photo of her kissing her boy in front of the Eiffel Tower, the reality star-designer, 28, Twittered: "In the City of Lights with my True Love."
Richie is headed to London Friday to launch her spring Winter Kate line at Selfridge's department store and debut her House of Harlow 1960 shoe and jewelry lines.
Her father, Lionel Richie, recently gushed to UsMagazine.com about his daughter's engagement to Joel Madden.
"My happiness for Nicole and Joel knows no boundaries," he told Us. "They have given me two beautiful grandchildren, Harlow and Sparrow, and have proven to be great parents."
