Could Ramona Singer really be pregnant?

In a preview clip from Thursday's Real Housewives of New York City season finale, the 54-year-old Bravo star tells close pal and costar Sonja Morgan that she may be expecting her second child.

"[My boobs] are like melons now," Singer tells Morgan, 47. "I haven't even told [my husband] Mario that I'm late yet."

During Singer's confessional, the Pinot Grigio aficionado adds that her "breasts are huge and they hurt. The last time they were like this was when I was pregnant with Avery."

The Real Housewives of New York City finale airs Thursday at 10 p.m. EST on Bravo.
