The couple dated for just over a year before calling time on their relationship late last year (19). However, they are now back together, and the "Price Tag" star is paying no attention to her critics.
Alongside a clip of her and Channing, 39, exchanging kisses while attending the MusiCares Gala together on Friday night, January 24, the 31-year-old singer wrote: "When you put the outside whispers, noise and comparisons on MUTE and turn YOUR life volume UP full blast."
"When you surrender and fearlessly act on the truth that always was. Love GLOWS and GROWS in a different way. Happiness from the inside out."
She added: "I love you so much baby @channingtatum. The way you love me and the way I love you and the way we feel it is all that matters."
"Magic Mike" star Channing recently defended his girlfriend against "hurtful" comments from trolls online, telling one fan: "If you can't not be a horrible hateful person on my page and support the infinite and untouchable beauty and woman that Jess is... please kindly get TF (the f**k) out of here. No one wants you here. Especially me."
