Lennon & Maisy Stella are singers on ABC's

Lennon & Maisy Stella are singers on ABC's "Nashville," and these pint-sized singers now have backup -- the most powerful talent agency in Hollywood.

The real life sisters -- who play TV sisters Maddie and Daphne Conrad -- signed with CAA.

In case you don't know ... CAA reps a constellation of stars, including Jeniffer Aniston, J.J. Abrams, George Clooney, Tom Cruise, Carrie Underwood and Kanye West.

According to the contract -- They'll have to shell out 10% of what they make -- but in return they'll get the services and experience of two of the agency's heaviest hitters.

The bad news ... 10% of their salaries goes bye bye.

Fun Fact:  14-year-old Lennon and 9-year-old Maisy are the daughters of Canadian country music duo, 'The Stellas.'

Justin Bieber..High Charity Roller..Drops $545K

Justin Bieber put on a shirt ... and a dazzling display of humanitarianism at a celebrity gala in Cannes, where he dropped $545K ... for charity.

Bieber -- all gussied up in a black, double-breasted suit -- hit up the amfAR gala, which raises money for AIDS research. People started making huge pledges of money -- one wealthy gent pledged $545K and Bieber -- quietly and without fanfare -- matched it.

We're told the crowd -- which included Leo DiCaprio, Heidi Klum, John Travolta, and Sharon Stone -- was stunned. Justin was asked if he seriously wanted to pledge such a huge amount and he said yep. Biebs said he just felt inspired to do something good.
