Miranda Lambert enjoyed a date night earlier this week. However, it doesn't appear to have been with her boyfriend, Anderson East.

Although the 32-year-old country singer and her R&B singer beau appear to be going strong just months into their romance, Lambert's latest date was with a "lady."

"Date night with the pink lady... #musicismedicine #blurrywords #sharppencil #notebookpaper #pinkguitar @gibsonguitar," Lambert captioned the photo below.

Lambert and East began dating at the end of last year, months after her former husband, Blake Shelton, filed for divorce, and after the news of the new relationship went public, Shelton reportedly found out about his ex-wife's new relationship from his mother.

“Blake’s mom told him about Gwen and Anderson West dating after reading about it on the Internet,” a source told Hollywood Life in late December, one month after Shelton went public with his own new romance. “He did not call Anderson and had no plans on doing so.”

While Lambert initially stayed silent in regard to her romance with East, she confirmed their romance in January with an Instagram photo of them cuddling, and was later seen joining him on stage during a concert on Valentine's Day.

Around that time, a source spoke out, claiming things between Lambert and East were getting serious.

"They both have discussed wanting kids one day," a source told E! News. "When they are both not on tour, they are with each other. They video chat or text and keep connected every day."

They've also met one another's families, and East is a big fan of Lambert's animals -- all 15 of them!

"Anderson loves all 15 of Miranda's animals," the insider shared. "They both are very into helping make a difference. Miranda is definitely in love with Anderson."

Lambert is also a fan of her ex-husband's new romance with Gwen Stefani, and, according to the source, is glad "they are happy."

"She is in the best place of her life now and looking forward to the future!" the insider added.
