Katie Maloney still isn't engaged, but could she be pregnant?

Katie Maloney Talks 'Vanderpump Rules' Season 4

In a new fan photo, shared online at the end of last month, the Vanderpump Rules star appeared to be sporting a visible baby bump.

"The day we became best friends. Team Katie!" the fan captioned the Twitter photo. "Thanks for the pic #reallife #bestdayever @MusicKillsKate @twschwa."

Katie Maloney Looks Back On Her Friendship With Stassi Schroeder

Although Schwartz favorited the tweet, he didn't re-tweet it to his own fans, and neither did Maloney.

Then, a week later, Schwartz and Maloney made another public appearance, and this time, Maloney was wearing all black. In a photo shared on Twitter by Mike Weaver, Maloney was seen standing next to her boyfriend, and wearing a loose-fitting black shirt with black pants.

Ironically, Maloney spoke out about starting a family just days ago. During an interview with Cupid's Pulse on Monday, the reality star said she wasn't quite ready to start a family with Schwartz, but also said she didn't want to wait too much longer.

“I definitely want us to enjoy being married for a bit before we start having kids," she explained, "and that’s why I want to get the ball moving — I’m young, but I’m not getting younger!”

As for Schwartz's future proposal, Maloney said it could happen at any time.

“We’re in the best place that we’ve been in," she said. "We went through hell, and we decided that our relationship is important to us both. We’re committed equally to it, and I think we’re more in love than we have been.”
