Who is the two-year-old stud dating?

Hilary Duff Opens Up On New TV Show & & Who She Would Be On 'Sex And The City

On Sunday, Venture Capital Post mentioned that Hilary Duff and Mike Comrie's son, Otis, is dating Jack Osboune's daughter, Pearl Osbourne.

When Duff posted a photo of Otis on Instagram with the hashtag, #justlookinforpearl, speculation increased that he and the star's daughter were a very young item.

Duff also tagged Osbourne's wife, Lisa, in the post which pretty much confirmed the speculation.

In the photo, Otis was seen walking barefoot in water and rocks as he appeared to be mid-sentence and happily trotting along.

This isn't the first time the two tots were seen on a (play)date together. Last month, Duff posted a photo of the two on Instagram again.

This time, the two were eating ice cream together during their 'ice cream date."

"Luca&Pearl's ice cream date @mrslisao we made some cuties," Duff captioned the photo.

Lisa also posted a similar picture on the social networking site of the two.

She captioned her picture: "Two of the sweetest babes I know, Luca & Pearl! @hilaryduff #icecream #gelato."

It seems the kiddos are spending lots of time together now that Duff is filing for divorce from her estranged husband, Mike Comrie.

TMZ reported that Duff wants full custody of her son, Luca, and wants Comrie to have visitation but is worried that his partying and drinking may interfere with his well-being and could adversely affect their son.

The former couple reportedly signed a prenup when they wed, but neither are struggling with finances. Duff allegedly just wants to make sure her earnings and possessions remain hers.

The two married in 2010 and when they separated, Duff's mom, Susan, reportedly said, "They're better friends than a married couple."

The two, though divorcing, will likely remain civil for Luca.

"We're constantly seen together and people are like, 'What are they doing? Are they back together? Are they not?' We're really good friends and we have so much respect for each other and obviously Luca is our No. 1 priority," Duff told E! News.
