Rita Ora thinks Gwen Stefani is “one of the sexiest moms on the planet”.

The No Doubt crooner shares three sons with her husband Gavin Rossdale and she gave birth to their youngest boy Apollo on February 28.

Rita thinks Gwen’s ability to balance home life with extensive professional obligations is incredibly attractive.

“[She’s] one of the sexiest moms on the planet,” she told MTV News.

Rita, 23, is planning to release her second studio album in September.

And she dreams of collaborating with Gwen on a song in the near future.

“There’s this lady, who I’ve loved since I was young and I’ve said it all the time, has an amazing family and etcetera, so it’s a bit of getting the right time, but Gwen Stefani is the one…” Rita gushed. “There’s been talks and there’s been things, but she’s just had an amazing baby, obviously real life hits, but we will figure it out. It’s all about the timing, but the song is there, I’m just really kind of waiting for her to just be like ‘boom,’ but we don’t force things like that. They just happen.”

While Gwen is preparing to become a judge on TV talent competition The Voice USA next season, Rita is busy wrapping up tunes for her new album.

The star loved working with her boyfriend Calvin Harris, as he proved to be a great help throughout the writing process.

“We actually did four songs together,” Rita said. “We didn’t plan it. It’s not like a Cher and Sonny situation. We were both kind of talking about music and we just happened to hum together and a song came out, and we ended up doing four tracks on the record, and it’s probably the best decision I made working with him.”
