During a Thursday appearance on The Tonight Show, Selena Gomez, 18, told host Jay Leno that her baby-faced boyfriend recently earned her mother Mandy's seal of approval.
"He passed the test," the Monte Carlo star said.
Bieber's family seems equally smitten with Gomez after they were introduced Memorial Day weekend. "They looked like one big happy family," an onlooker said of the couple's outing with Bieber's father, Jeremy, and his half-siblings, Jazmyn and Jaxon. "The kids took to Selena straight away and they were all laughing and joking around. They couldn't have been happier."
