Ms. Jackson is still NASTY!

She may be 44 years old but Janet still has it going on!

After losing her brother a little over a year ago, and playing Patricia in Tyler Perry's hit movie "Why Did I Get Married Too," the singer rocked the stage at the Essence Music Festival this past weekend.

Check out the video below, it's a little blurry but you'll get the point around a minute in. (Silent prayer: I hope my but looks that good when I'm over 40.)

One writer, Mark Marino, posted that Janet is channeling "Rihanna, Beyonce, Lady Gaga," etc... little does that author know that Janet was doing this before Gaga or Ms. RiRi turned ten years old.

Dear Mr. Marino, get your facts straight honey... who do you think influenced some of these ladies? Performance wise, she has them beat. There is no way they can top her Velvet Rope concert at Madison Square Garden. Beyonce has the voice. Rihanna has the? Management team and writers??? And Lady Gaga has the talent and weird factor. But Janet Jackson is a born performer, amazing entertainer, and is still fabulous and over 40.

To Mr. Marino and the haters who are telling Janet to 'sit down,' do me a favor and shut up. Now... stare them down Janet. And do like your brother and keep showing them who's bad!
