Justin Bieber is single these days, but he may not be totally over his ex-girlfriend Selena Gomez.

Biebs was spotted spending time with a Gomez lookalike while on vacation in Miami.

On Tuesday, Bieber enjoyed a family lunch with his younger brother Jaxon at hotspot Seaspice. Bieber docked his yacht nearby for the lunch, and as soon as the brothers were done dining he invited model Alexandra Rodriguez to join him and Jaxon on the yacht.

The brunette and Bieber lounged on the yacht and drank Dobel tequila cocktails.

A source tells FOX411 though Rodriguez arrived at the restaurant with friends, she quickly ditched them “in exchange for some quality time” with Bieber.

A spy said after Bieber and Rodriguez went swimming, she changed into the pop star’s clothes.

According to Us Weekly, Rodriguez is a 24-year-old model. The site reports Bieber was seen wrapping his arms around Rodriguez affectionately.
