With new episodes giving fans an inside look at the fallout from Singer's messy divorce from husband Mario, Singer has turned her attention to weight loss, and shared an impressive photo with fans on Twitter.

"Have my work cut out for me to get back into swim suit shape. Who else is on this mission?" Singer asked fans on Twitter last week, along with a photo of herself in yoga pants and a shorts bra.

Last year, before filming began on the seventh season of The Real Housewives of New York City, on which Singer has starred since season one, her husband began making headlines for his alleged affair with Kasey Dexter. As soon as the reports hit the web, fans wondered if the pair was headed for divorce, but despite Singer's filing in early 2014, the couple decided to give their marriage another shot, and remained together until the summer of that year.

Months later, Singer began filming with Bravo, and chose to include the ongoing drama between herself and Mario.

Now, as she embarks on single life in the Big Apple, Singer is determined to get her pre-divorce body back, and recently shared a photo of her goal.

"This was me last summer 5 lbs lighter," she wrote. "Ugh hope I can get there again."
