Christina Aguilera put her growing baby bump on display when she went on a shopping trip with fiancé Matt Rutler in Beverly Hills on Saturday. The expecting singer appeared to be in a cheerful mood as she exited a Barneys New York store, and even flashed a "hang loose" sign as she walked with Matt. Back in March, Christina confirmed that she is expecting a baby girl with Matt, whom she started dating in 2010. The singer already has one son, Max, with ex-husband Jordan Bratman. Christina is currently taking an extended break from The Voice, where she serves as a coach alongside Adam Levine, Blake Shelton, and CeeLo Green. She was absent for the show's most recent season (during which she was replaced by Shakira) and will see Gwen Stefani take over her role in the coach chair in the upcoming seventh season. Christina was excited about Gwen joining The Voice team, tweeting back in April that she was "so excited" to welcome the No Doubt singer to her "crazy fam."
