Cole stepped out last month in a curve-hugging dress that seemed to show off a growing baby bump.
Liam Payne couldn't be happier -- but he isn't ready to reveal why just yet.
The 23-year-old singer took part in an #AskLiam Twitter Q&A session on Saturday, and while he dodged questions about rumors that he's expecting his first child with girlfriend Cheryl Cole, he did admit to being one happy camper.
"Are you happy honey?" one fan asked the One Direction singer.
"The happiest I could be," he sweetly replied.

The couple first met in 2008 when Payne auditioned for the X Factor. They started dating this past February.
