The Rolling Stones are to record their first album in 10 years.
The 'Wild Horses' hitmakers, Sir Mick Jagger, Keith Richards, Ronnie Wood, and Charlie Watts have been in a London studio over the past week working on a follow up to 2005 record 'A Bigger Bang', and morale is high after Ronnie revealed he is going to be a father to twins at 68.
A source said: "Ronnie broke the news on one of their first days back in the studio and they were all delighted for him. It's given everyone a great boost.
"The guys booked in for a few sessions to lay down some tracks which Mick and Keith have written. It's very early stuff - just four or five songs at the moment - but the plan is to make a full new album in the new year."
The band - who have a combined age of 285 - are heading to Latin America for a 12-date tour in February, entitled 'América Latina Olé Tour 2016', kicking off their run of shows in Santiago, Chile, on February 3 and then heading onto Argentina, Uruguay, Brazil, Peru, Colombia and Mexico.
Mick, 72, was spotted in Cuba earlier this year which led to local papers reporting the rockers are set to play a concert in the communist country in March 2016 - and they are now said to be keen to record their adventure.
A source added to The Sun newspaper: "The band are planning one big stadium show in Cuba and want to make a film about it too.
"They're also getting together in April to attend the opening night gala of Exhibitionism, their massive exhibition at the Saatchi Gallery in London. It's an exciting year."
In November, Ronnie hinted the band will be working on new material this month.
He said: "We'll maybe go in the studio in December and cut a few tracks and see what happens.
"We'll take it from there, see how it all goes. One thing at a time."
Keith, 71, also recently revealed he is keen to get the group back in the studio.
He said: "These guys aren't getting any younger, but at the same time, they're getting better.
"I'd love to shove them in the studio in April, hot off the road."
