Chris Brown recently shared photos of baby girl Royalty for the first time on Instagram: How did on-again, off-again girlfriend Karrueche Tran react?

The R&B star took to his social media account on April 16 to confirm his fatherhood in a couple of adorable images.

The first snapshot sees Brown rocking a matching red hoodie with his 10-month-old daughter, calling her his "twin." He then added another picture of his princess sporting her cute brunette curls, appropriately captioning it with a crown emoji.

According to HollywoodLife.com, Tran was shocked at first to see her ex-boyfriend's Instagram posts - to the point that she dropped her phone. However, when she looked at them again after composing herself, she "smiled."

A source claimed that the model is happy and proud that the "New Flame" singer is finally "growing up" and "taking care of his responsibilities."

"She's so happy Royalty has her father in her life," the source added. "It's something she wishes she wish she had when she was Royalty's age."

Meanwhile, Brown has not reconciled with Tran. However, he is supposedly planning on proposing to her very soon -- on May 17, when she turns 27.

Another source recently told HollywoodLife.com that the "Loyal" hitmaker has repeatedly been watching the model's emotional OWN interview, which has made him think about "her wiggling her ring finger and saying she'd marry him."

As a result, Brown is reportedly considering giving Tran a diamond engagement ring on her birthday, especially because he knows that is what she has always wanted, even right before their recent split.

"When they've discussed the idea in the past, she lit up like fire," the source continued. "She was so happy and told him she'd love to be Mrs. Brown."

The source insisted that Brown sees Tran in his future, adding, "If marry her is what it's going to take to have her, he's considering it. He wants to step it up and show her he's serious about her, their relationship."
