Luann de Lesseps seems to have already moved on from her ex-husband, Tom D'Agostino Jr.

On Monday, the "Real Housewives of New York" star took to Instagram to share a clip of herself driving a boat. De Lesseps appeared to be having a blast in the clip and even showed off her bikini body. "It matters not how straight the gate, I am the captain of my...? #i #am #Happy #captain #end #of #summer," she wrote in the caption.

De Lesseps' post comes just a month after her split from D'Agostino, which she announced on Twitter. The pair had been married for seven months. "It's with great sadness that Tom & I agreed to divorce. We care for each other very much, hope you respect our privacy during this sad time!" the reality star wrote.

When de Lesseps announced that they were divorcing, a number of fans were not surprised with the news. "Everyone saw this coming...... I feel sorry for what you are going to have to listen to from Sonja and Ramona, & all the other litter snipes," one follower commented.

Another user added that D'Agostino never seemed to genuinely care about her. "I agree. He looked like he wasn't into LuAnn. His facial expressions at the events say it all. Especially @ Ramonas house," another follower commented.

Perhaps the split did not come as a surprise to many as a month before D'Agostino and de Lesseps broke up, they had already been plagued with breakup rumors. However, D'Agostino slammed the rumors at the time, claiming that "there is a lot of love" between him and his then-wife and that they wanted to make their marriage a success.

De Lesseps also echoed the same sentiments during her interview with People less than two weeks before her breakup tweet. "Tom and I are in love, and marriage takes work," she said. "We are working on this together."

Despite de Lesseps and D'Agostino's united front, some sources revealed at the time that their marriage was doomed. The couple reportedly hit a "major rough" patch before they tied the knot, but de Lesseps was "too embarrassed" to call their wedding off so she went through with it. But as many expected, their marriage did not last long.

Just a few weeks after their split, D'Agostino reportedly went back into the dating game. He has been seeing a few women, but a source claimed that he has not yet gotten serious with anyone in particular.
