Christina Aguilera has a little diva on her hands! The 34-year-old mom of two shared the first photo of 5-month-old daughter Summer Rain rocking a hot pink dress with a diaper that had "Lil Diva" written across the bottom.

"Watch out... another one's getting ready to conquer the world! #driven #diva2," Aguilera captioned the super-cute photo.

"The Voice" judge, who returns to the panel for Season 8, gave birth to Summer in August. It's the first child for Aguilera and her fiancé Matthew Rutler and the second for the "Beautiful" singer. She also has a 6-year-old, Max, with ex-husband Jordan Bratman.

Aguilera took time off from "The Voice" to give birth and was temporarily replaced with Gwen Stefani. NBC announced in October that the "Lady Marmalade" singer is expected to return for the new season. Page Six previously reported that there were some issues with Aguilera's return because certain staffers were hoping Stefani would stick around.

"When Gwen took over, she instantly became a favorite and bonded" with the other judges, the source said. "She injected energy and humor onto the panel."

However, another source told the site that there was no truth to the report and everyone is happy to welcome Aguilera back to the show.

"Whenever there's a change in couches, there are rumors of drama," the source told Page Six. "Christina was always coming back. And Gwen is always welcome- hopefully she'll be back."

According to Hollywood Life, the "Hollaback" singer never expected to stay on the show long-term and used it to help boost her career. 

"For Gwen to do 'The Voice" is a re-launching pad for things she wants to do in her career. She is going to work more on fashion, music and other things, now that she has a fresh coat of paint on her from the exposure of 'The Voice,'" a source said. "But one thing for sure is she will be back on 'The Voice' in the future. 100 percent. They all love her there."
