Jan. 26 (UPI) -- Chrissy Teigen says daughter Luna is going through a "nurturing, motherly" stage.
The 32-year-old model and television personality, who is expecting her second child with husband John Legend, said in an interview with PopSugar that Luna is obsessed with dolls but not quite ready to welcome a sibling.
"She is in this weird baby stage," Teigen shared. "A really nurturing, motherly stage -- and I think [all toddlers] get there, even when their mothers aren't pregnant. She's piling in baby dolls all into her strollers and pushing them around."
"Maybe I'm underestimating her, but I think when I start breastfeeding and this thing comes out, that's when she's going to be like, 'What?'" she said. "Which I'm kind of excited for, because she's very much a daddy's girl, so I think that jealousy might be kind of good for her."
Teigen announced in November that she's expecting again via in vitro fertilization. She said in an interview with E! News this month that she promised Legend she'd keep the baby's sex secret, but told PopSugar she hasn't done a great job.
"I keep wanting to just say it because everyone knows everything about us, but he wants to have one thing for us," the star said of Legend.
"I'm shocked it hasn't been anywhere," she added. "I mean, at Lip Sync Battle, I have a hot mic. It's always on ... I will never remember that I'm mic'd, ever. I'll run up to celebrities, and they'll be like, 'What are you having?' I have told thousands of people."
Teigen and Legend welcomed Luna in April 2016. The model shared a sweet moment with her daughter at the playground in a new photo this month, writing, "Weeeee are very skeptical of slides right now."
