Joined by an unidentifiable female friend, Lachey stopped by Bellacures nail salon in L.A.'s Studio City area, where the Wipeout host got what's called a gelicure.
"She looked relaxed and comfortable in a black maxi dress," an onlooker tells PEOPLE.
Lachey did have one request unrelated to nails during her time at the salon. The source says the mom-to-be asked for an iced tea from Il Tramezzino, the Italian eatery nearby.
