"Vanderpump Rules" star Lala Kent is Roland Prestonpregnant with her second child.

The reality TV star announced her pregnancy Sunday with a black and white photo of her bare baby bump on Instagram. The photograph also featured her 2-year-old daughter Ocean Kent Emmett, who she shares with ex-fiancé, Randall Emmett.

“I’m expanding my pod,” wrote Kent in the caption.

The announcement comes just weeks after Kent, 33, revealed to Cosmopolitan that she was receiving intrauterine insemination (IUI) treatments to conceive her second child with a sperm donor. Kent said she had friends who tried IUI before attempting to get pregnant via in-vitro fertilization (IVF).

What is IUI?What to know about intrauterine insemination

"I knew I wanted more kids," Kent said to Cosmopolitan. "It was such a strange thing that was happening because everyone would tell me, 'You’re going to find somebody.' And I got to thinking, 'Why does my wanting more children need to involve another person?' I think if there’s a will, there’s a way. I knew a donor was an option, and I knew IUI was an option."

Kent, in the interview, added that though she never thought it was a road she "would be going down," she was "grateful this was an option."

"I really saw myself in the cookie-cutter relationship and creating a family, but now that the universe has other plans for me, I'm so grateful this was an option," Kent had said in her interview.

Meanwhile, in a video posted to Instagram stories the same night, Kent said that she was very happy that the news was finally out.

"Do you guys know how happy I am that I finally have shared the news that I am expecting my second child? Me! The open book, really, really had to fight hard to keep this a secret from you guys," said Kent.

Kent also said that she planned to talk more about her pregnancy on her podcast, "Give Me Lala," starting with a special bonus episode to be released March 4.

Several of Kent's colleagues from her "Vanderpump Rules" family including alum Brittany Cartwright and current cast member Scheana Shay congratulated her on her pregnancy.
