Los Angeles, Nov 17 (IANS) Model Hailey Baldwin subtly confirmed her marriage to pop singer Justin Bieber on social media by changing her last name to Bieber.

On Friday, the 21-year-old model changed her Instagram handle to "Hailey Bieber" even including her married last name in her bio, reports people.com.

"Hailey Rhode Bieber," the daughter of Stephen Baldwin wrote.

Also on November 15, Justin confirmed their marital status.

"My wife is awesome," he captioned a photograph of the pair smiling and holding hands.
