After the launch of Beyonce's new album Lemonade - which appears to hint her husband Jay cheated on her - Solange reportedly "couldn't be happier".
A source told HollywoodLife.com: "Solange knows that Bey’s had to be quiet about some things in her marriage. She hates that Beyoncé has lived with pain and is really happy that she’s finally broken out and is talking about it."
"With this album, she thinks Bey has eclipsed herself by opening herself up and being a voice for women."
Last night Beyonce's mum Tina Knowles praised her daughter for "coming out the other side".
Tina took to Instagram following Beyonce's big album reveal to say how important it was for the singer to show that it is possible to bounce back.
"No matter what you’ve gone thru in life you can always come out on the other side! (sic)."
In the newly released tracks, Beyoncé sings: "Looking at my watch he should have been home. I regret the day I put that ring on ...
"My daddy warned me about men like you cause every promise, don't work out that way. Nothing seems to hurt like the smile on your face."
She also appears to reference her tragic miscarriage.
The fiercely private singer lost a child before she conceived daughter Blue Ivy with husband Jay Z, and has only spoken once about the trauma.
Before the track Sorry, Beyonce sings: "So what are you gonna say at my funeral now that you've killed me? Here lies the body of the love of my life whose heart I broke without a gun to my head.
"Here lies the mother of my children both living and dead. Rest in peace my true love, who I took for granted."
