After Britney tweeted, "off on a romantic weekend with Jason for my birthday. xoxo Brit" and "I'm almost done with my new album and it will be coming out this March. I AM IN L-O-V-E WITH IT!", she added this cheeky holiday message to her Twitter page.

Of course, it's Queen B's birthday, so she thanked her fans as well, writing, "My fans mean the world to me & waking up to all of your wishes really made me smile, so here's something that I hope will make you smile..."

Think Britney's team signed off on this? Eh, might as well let her have a little b-day fun...
