Real Housewives of New Jersey star Dolores Catania is proving that there's no bad blood between herself and ex-husband Frank Catania. 

This week, the reality star 53, attended the bridal shower of Frank's new fiancée Brittany Mattessich.

The former corrections officer wasn't the only Jersey Housewife in attendance, with Melissa Gorga and newcomer Rachel Fuda also coming to celebrate the happy occasion. 

Posting about the event on Instagram, Dolores wrote, 'Had so much fun showering the beautiful bride-to-be. So excited for these two [Frank] & [Brittany].'

Brittany posted about the party on her own page, writing, 'Showered with LOVE! Thank you to all my friends and family who came out and celebrated this special day.'

Dolores decided to dress conservatively for the occasion by donning an ankle-length floral frock with billowing sleeves and ruffles. 

Margaret Josephs, who wasn't at the event, commented on Dolores' post, 'Congrats to [Brittany] and [Frank]!! I'm so sad I missed this fabulous celebration!! You all look stunning!'

Frank, 59, got engaged to Brittany, 34, last October after popping the question in a very romantic way.

The bodybuilder surprised his bride-to-be with a flower wall of red roses, along with a lighted sign that read, 'Will you marry me?'

The answer was 'yes,' because Brittany shared photos of the two standing in front of the wall and flashed her multi-carat engagement ring to the camera.

'We're Engaged!!!!'' she announced in a post on Instagram last year. 

'I'm so excited to start this next chapter with you along with all the other good things we have going on…' she continued.

Frank and Dolores have been divorced since 1998 and share two grown children, Gabrielle, 26, a veterinarian, and Frank, Jr (Frankie,) 25, an asset manager
