Pop star Joe Jonas is no longer single - he is dating a Swiss-born model, according to reports.

The singer was spotted hanging out with Blanca Eggenschwiler on Thursday (29Nov12), before his Jonas Brothers concert at Hollywood's Pantages Theatre, and a pal appeared to confirm the new romance in a photo post on Twitter.com later that night.

Singer Jordan Baird, a finalist on the reality Tv competition show The Next which featured Jonas as a judge/mentor, tweeted a picture of himself with Eggenschwiler and Kevin Jonas' wife Danielle, alongside a caption which read, "hanging with the brothers (sic) ladies before the show".

The blog post has since been deleted, and on Friday (30Nov12) Baird simply wrote, "Great night last night with @joejonas@nickjonas @kevinjonas @daniellejonas & some other amazing people. Going at it again tonight!"

Model/graphic artist Eggenschwiler is based in New York, where the Jonas Brothers recorded chunks of their forthcoming as-yet-untitled album this summer (12).

Jonas, 23, has previously dated country star Taylor Swift and actresses Camilla Belle and Twilight beauty Ashley Greene .
