On Thursday, the 36-year-old singer posted a photo of her growing baby bump adorned in Henna tattoos on Twitter. In the pic, Morissette is surrounded by several friends, who were also decorated in the ceremonial paste.
"Some rituals surprise in the heart-warming department," Morisette explained of the design.
In Arabic culture, the temporary skin decorations are typically applied during the seventh month of pregnancy.
On Wednesday, the "Hands Clean" singer exclusively confirmed she and husband MC Souleye are expecting a boy. Their son is due in early 2011.
