(CBS News) The Rolling Stones hit the studio last week in Paris, marking more activity surrounding the group's 50th anniversary.

Frontman Mick Jagger tweeted a photo of himself surrounded by guitars, along with the caption: "Had fun in the Paris studio this week! @RollingStones."

The band members were also photographed leaving a recording studio. There's no official word on whether they're recording a new album, but if that's what's in store, it would mark the band's first new full-length effort since 2005's "A Bigger Bang."

Back in April, guitarist Ronnie Wood told he was keen for a reunion; it was just a matter of timing. And by the sound of it, the timing is all coming together.

Earlier this summer, the Rolling Stones unveiled a new logo and reportedly teamed up for a few rehearsals. They also appeared together at a photography exhibit and book launch in July.

There's been buzz about an upcoming tour as well. In July, Jagger told The Evening Standard the band may play live as early as this fall, adding, "You will definitely be seeing us all together soon. It's been great fun being back together and there are a lot of memories in here. I can't believe it's been 50 years. We've been hanging out together, seeing quite a bit of each other and we want to do some gigs."

Also in the works is a documentary, due out this fall.
