The songstress had previously expressed her desire to have more kids during her bombshell court hearing in June.
Britney Spears and Sam Asghari are toying with their fans. On Monday, the 39-year-old singer and the 27-year-old model joked about welcoming a baby together, with Asghari sharing a clip of Britney dancing with a baby doll.
"Exclusive! We had a baby ����What should we name her?", the fitness trainer wrote over the video on his Instagram Stories. "Oh, look at that! You look just like each other", he quipped as his fiancée gave the doll a kiss.
"She's talented, got that choreography down", Asghari joked in a follow-up video, with Britney adding, "She's a natural like her mama" as they both broke into laughter.
Although the couple —who became engaged on September 12— were only joking with the baby doll, Britney previously expressed her desire to become a mom during her bombshell court testimony earlier this year.
"I don't feel like I can live a full life", the songstress stated of her conservatorship, under which her father Jamie Spears and others have decided over her estate for the past 13 years. "I want to be able to get married and have a baby."
Britney is already a mom to sons Sean Preston and Jayden James —who recently turned 16 and 15, respectively— with ex-husband Kevin Federline, whom she was married to from 2004 to 2007.
