That was quick!

Luann de Lesseps is out of rehab three weeks after entering treatment and hitting the ground running with her cabaret show, E! News reports.

"She will be spending the day tomorrow rehearsing her cabaret show before Saturday's performance. Luann knows there will be a lot of eyes on her this weekend, but she is healthy, feeling well, in good spirits and is ready to put on a great show for her fans," a source dished to the site.

It's been a rough couple months for the Real Housewives of New York star. She was arrested for being drunk and disorderly over the holidays in Florida, and earlier this month her ex and two kids filed a lawsuit against her. Despite it all, she's ready to move forward.

"Thank you so much for all of your support. I wanted you to know I’m doing great, & I hope you’ll come and see me on Aug 4th in Long Island @theparamountny or Aug 24th in Atlantic City @borgataac Looking forward to being back on stage!!!" she wrote on Instagram.

Let's hope she can keep it together this time around!
