Patrick Schwarzenegger is dating Abby Champion.
The 22-year-old hunk - who split from singer Miley Cyrus in April last year - and the model appear to have confirmed they are an item after she posted a loved up picture of the pair with his arm around her waist.
The blonde beauty shared the image on Instagram from her 19th birthday celebrations over the weekend.
Patrick is thought to have been getting cosy with his new blonde beauty since September.
Sources close to Patrick - who is signed to the same modelling agency as Abby, Next Models in Los Angeles - told New York Post's Page Six column: "Their relationship has heated up quickly. She knows all of Patrick's close friends by now."
Patrick and Abby were spotted playing beach volleyball in Miami on Wednesday (02.03.16).
The star, who is son of actor come bodybuilder Arnold Schwarzenegger, attended his mum Maria Shriver's star-studded 60th birthday party at the Montage Hotel in Beverly Hills in November last year.
Among the star-studded guest list was Oprah Winfrey, Tom Hanks and Stevie Wonder.
The couple were joined by a group of friends as they posed for a photo booth snap to mark their relationship.
