Jessica Simpson and Eric Johnson – who welcomed their daughter in May – are expecting another child, according to reports widely circulating online.
When asked about the latest baby buzz, Simpson's publicist told PEOPLE, "I'm not going to comment on this speculation."
The star and Weight Watchers spokeswoman, 32, (who showed off her 60-pound weight loss this month) called Maxwell's birth "the greatest experience of our lives."
In May, she told PEOPLE, "I don't want to have another baby right away but I do want to have more kids. Having babies back to back has to be so hard."
Having baby No. 2 is all about timing, she added during the interview about becoming a mom.
"I really want to give Maxwell all of the attention and all of the love and time that I possibly can give her," she said. "When I feel like it's the right time to bring another little one into the family, I will. I won't wait too long but I won't do it immediately."
Simpson and former NFL player Johnson, 32, started dating in May 2010 and were engaged six months later.
Tweeted Simpson this month: "I am so grateful for my new lil family! Happy Thanksgiving everyone!"
