Playing Gwen Stefani Is Pretty in Pink and All Smiles Amid Gavin Rossdale Alleged Nanny Affair Reports

Gwen Stefani is not letting any recent drama get her down.

The 46-year-old singer smiled big as she arrived at a sound studio in Los Angeles on Thursday, appearing to be in remarkably good spirits despite a report breaking on Wednesday that her ex, Gavin Rossdale, had been carrying on a three-year affair with their childen's nanny.

A source told ET on Wednesday that 50-year-old Rossdale had allegedly been cheating on Gwen with the family's nanny, Mindy Mann. As first reported by Us Weekly, the No Doubt frontwoman is said to have learned of the alleged relationship after discovering explicit text messages -- reportedly including nude photos and plans to meet up for sex -- between Mann and Rossdale on the family's iPad in February. Reps for Stefani and Rossdale could not be reached for comment.

Stefani's huge smile on Thursday marks a sharp contrast from her emotional showing on Wednesday night's episode of The Voice. When she was forced to choose which of her singers -- Korin Bukowski, Ellie Lawrence, Regina Love or Viktor Kiraly -- she would save from elimination in the competition, she visibly fought back tears.

"Honestly, I am so blown away by this whole experience, I cannot believe," she said. "You guys are saving me, you know, you are saving me."

Stefani and Rossdale announced their split after nearly 13 years of marriage in August. She's since publicly moved on with her fellow Voice coach, 39-year-old Blake Shelton.

On Thursday, Shelton made light of all the tabloid rumors surrounding their new relationship, including one that claimed Stefani was pregnant with his child. When one of his followers joked, "@blakeshelton I just read that I am having your love child," he responded, "Ha!!! You too!!! Damn I'm fertile!!"
