The on-again, off-again Voice mentor walked the red carpet on Thursday for an event to do with Verizon's HopeLine program.
Us Weekly got to the goods right away since Xtina is planning her 2016 return to NBC's singing competition.
"I’ve known Gwen for a really long time,” she told US Weekly. "We went to each others' kids birthday parties, we share the same management, and Blake I know now from the show. The two of them are both great people. Gwen's such a great mother and a hard-working mother too! It's not easy to juggle 'The Voice' and music and children — it takes a strong woman. And obviously I'm always in support of that. And I do know what it's like to go through a divorce myself, and it's tough!"
And because both Gwen and Blake announced their divorces to Gavin Rossdale and Miranda Lambert (respectively) over the summer, the divorced mother of two had some advice for her friends.
"I keep telling them both to stay strong and have fun!" she added. "Divorce and life is hard enough! If you find someone who makes you happy, you gotta go for it. So they deserve it and they deserve to be happy!"
