Happy 20th birthday, Jamie Lynn Spears

Britney's younger sis has been laying pretty low lately being a mom to daughter Maddie in Nashville, but she shared a sweet photo of them this weekend and tweeted "What else do you do on your 20th birthday weekend?"

 It doesn't sound like Britney was on hand for the celebrating, as she was busy with her boys in another city this weekend...

The Femme Fatale spent the weekend in Vegas again and brought along boyfriend Jason Trawick and sons Sean and Jayden.

The group had a private suite at the Palms Casino Resort with 24 hour security guards stationed outside the room. But they didn't keep to themslves all weekend.

They headed to Nove Italiano Friday night, where they ate in a private dining room. Britney also hit Tao nightclub in the Venetian Hotel. And on Sunday afternoon, Brit took her boys to catch The Lion King at Mandalay Bay and meet the cast backstage after the show.

Back in Tennessee, it seems like Jamie is also loving being a teen mom.

She also shared a pic of her grilling for her daughter yesterday and a tweet today saying "goodbye teens.. HELLO 20's!!!".

Even though Jamie and Brit couldn't be together, Jamie is still one supportive sis.

"ya rocked GMA today B!!! Album in stores today-GO BUY it!!! @britneyspears," she tweeted last week after Brit's Good Morning America performance.

It's nice to see both Spears girls doing well and looking happy, right?
