Single siren! Joanna Krupa steps out in mini dress for lunch as split from husband Romain Zago becomes public.

Joanna Krupa stylishly stepped out for lunch in Beverly Hills on Monday as her split from husband Romain Zago became public.

The 38-year-old reality star put her long legs on display in a long-sleeved wrap-around floral print mini dress while dining at an Italian restaurant.

The Polish beauty also showed ample cleavage with a wide plunging neckline. 

Joanna completed her look with tan heels and accessorized with large sunglasses.

She wore her long blonde hair straight down below her shoulders and also carried a black clutch. 

Joanna and Romain, 44, have been separated since December, according to an article Monday by E! News.

'They just grew apart,' a source said of the couple who got married less than four years ago in June 2013 in Carlsbad, California.

Joanna did not spend her birthday last month with Romain and she stepped out last week in Los Angeles without her wedding rings on.

The blonde beauty used to regularly posts shots of herself with Romain on her Instagram account.

Those photos slowed down last year and she has not shared a pic with the nightlife guru since November. 

Joanna got her start posing for FHM, Shape and Maxim, then scored the cover of Playboy magazine.

She then did the TV series Superstars in June 2009 with Terrell Owens and later competed on season nine of Dancing With The Stars.

Since autumn 2010, Joanna has hosted and served as the head judge on the Polish version of Top Model.

She also was also one of the cast members on the Bravo reality show The Real Housewives Of Miami.
