Britney Spears is opening up about motherhood again.

The pop icon revealed in a now-deleted Father's Day Instagram post that she hopes to have another child someday, sharing the emotional message alongside a video of herself dancing while holding a small guitar.

"It's an emotional day for me," Spears wrote in the caption. "Guitars remind me of baby aliens,, such gentle strings,,, music is said to be the speech of angels,, I bought this one in Mexico 🇲🇽 in hopes one day I can have another baby."

In the video, the 44-year-old singer danced around her home wearing a yellow slip dress, black boots, and a fedora while strumming the miniature guitar. [That video, minus the now-deleted caption, can be seen here.] She later shared a second dancing video, this time dressed in black.

Spears is already the mother of two sons, Sean Preston, 20, and Jayden James, 19, whom she shares with ex-husband Kevin Federline.
