Fashion designer Billie, 26, is already mum to daughter Nell Shepherd, who turns two in July, and has admitted she'd love to add to her family in the future.
But could the future come sooner rather than later?!
Bobby thinks so!
In his most recent column for Reveal magazine, out now, the TOWIE favourite wrote about Billie and Nelly's recently holiday with sister Sam and Sam's son Paul, six months.
"Sam and Billie are having a sunshine break together with the young 'uns. It's so nice that there's such a small age gap between Paul and Nelly, as they'll grow up to be best friends, just like their mummies," he said.
"I still predict Billie will be expecting baby #2 by Christmas…"
Well, in a recent interview with us, Billie did say she wanted baby number two to arrive sooner than later!
"I definitely want to have another one soon," she said. "I don't want to leave it too much longer… I said I wanted another one straight after Nelly, but its' so nice to have that time with your first."
