Gomez defends her new boyfriend

However, some fans seemed to take issue with Gomez's new beau, leading her to comment further on Instagram in defense of their relationship.

"So why is he the best thing that ever happened to me? It's over," Gomez replied to one fan. In another reply, she said: "He's still better than anyone I've ever met. Fact."

In another comment, she wrote: "I don't get it. If you really cared about me. That would be the happiest thing I could be. If you don't, feel free to say what you want. But I never will Let your words guide my life. Ever. I've had enough. If you can't accept me at my happiest, then don't come into my life at all." All fans appear to have deleted their original comments.

After replying to these fans, Gomez shared a photo of her new rings, which include one with the initial "B" and a separate diamond on each end.

The history of Gomez and Blanco

After another Instagram commenter told her to "stop posting pictures of your boyfriend" if she couldn't handle the hate and said "don't be mad at your fans," Gomez responded that she and Blanco are already dating It's been a while.

"Not angry. It's been six months," she replied. "I will always defend my friends, family and fans until the day I die."

However, Gomez previously stated in a TikTok video in September that she did not have a boyfriend, and announced her single status in August with her latest song "Single Soon."

Regardless of the timeline, Gomez and Blanco have a history. Ironically, he co-produced "Single Soon" and also attended her 31st birthday party in July. But more than four years ago, she featured on Blanco's song "I Can't Get Enough," meaning they had years of friendship before falling into romance.
