The singer is married to motocross racer Carey Hart but the pair previously split for several months and then reunited when they both regretted ending their relationship.
The couple have both said that they want to start a family together and Pink has now finished her 'Funhouse' tour.
The 31-year-old was seen in a gas station in Beverly Hills, where her stomach reportedly looked bigger than usual when her purple top blew back.
Pink apparently did not seem concerned about her weight gain and was laughing and joking with Hart.
