Nicole Kidman and Keith Urban looked like the perfect family Saturday as they took daughters Sunday Rose and Faith to a friend's birthday party.

The girls clutched onto their parents the day after Kidman and Urban attended the Rolling Stones concert in LA. Urban even joined Mick Jagger and crew on stage for a rendition of "Respectable."

Keith Tweeted this photo of himself and the Stones after the performance. Check out the legends' collaboration in this video clip ...

Nicole Kidman and husband Keith Urban attended the Gold For Golden event at The Lounge at the New Equinox Flagship gym in Los Angeles on Saturday, which is a special inauguration for Hollywood and the Sporting Industries to get to know each other better during awards season, according to a press release.

The event honored Olympians including Ryan Lochte, Kerri Walsh and Gabby Douglas, and Jon Bon Jovi and Stacy Keibler were also in attendance.

Fox has announced that Nicki Minaj and Keith Urban will be joining Mariah Carey and Randy Jackson at the American Idol judges' table this season.

"It's really an honor to have been invited to be a part of the American Idol family," Urban said in a statement. "I'm looking forward to working with everyone and to seeing the same passion that I have for music in all of the participants."

Host Ryan Seacrest tweeted the photo below and wrote, "It's official, your new #IdolJudges are @MariahCarey, @NickiMinaj, @KeithUrban & @Yo_RandyJackson!"

After the departure of judges Jennifer Lopez and Steven Tyler earlier this year, it was announced in July that Carey would join the show, earning a whopping $18 million for the season. No word yet on what Urban and Minaj will be paid, but we'll let you know as soon as we find out!

Say goodbye to Keith Urban!

The country singer announced yesterday that he will not be returning as a mentor on the Australian version of The Voice in 2013.

"I've been so fortunate to have been a part of The Voice. And as much as I'd love to do it again, it's clear that the recording and promoting of a new album, a tour and other commitments will keep me from being a part of the second season," Urban said in a statement to Australia's Nine Network.

Nicole Kidman's hubby leaves behind fellow judges Seal, Delta Goodrem, and Joel Madden.

"To everyone who sang on the show, I thank you; you've inspired not just me, but countless others. To everyone behind the scenes and to my on-camera family - Darren, Delta, Joel, and Seal - thank you for making it so much fun," he added.

As sad as we are to see him go, we can't wait to hear his new tunes!

Sunday and Faith are little world travelers!

Nicole Kidman and hubby Keith Urban looked anxious to get back home as they escorted their two darling daughters through LAX, after arriving from a vacation in their native Sydney, Australia, on Thursday evening.

The Oscar winner held on tight to her one-year-old daughter, while Keith helped out by holding on to little Sunday's hand -- how cute is that little flowered dress?

The family spent time Down Under to celebrate Kidman's 45th birthday with friends and family, and they are also gearing up to celebrate Sunday's 4th birthday on July 7.

Happy birthday, girls!

Nicole Kidman and hubby Keith Urban packed up the girls and took them to Romp indoor play-place in Hollywood on Sunday.

The actress' one-year-old daughter Faith, with her incredibly rosy cheeks and bright red hair, held tight to mommy as they family made their way into the indoor playground. 3 1/2-year old Sunday Rose held Kidman's hand, with daddy close behind, shooting video of the trio on his cell phone.

Meanwhile, Nicole's other daughter, 19-year-old Isabella, is reportedly getting super serious with boyfriend Eddie Frencher, 23. Her adopted daughter with ex Tom Cruise met the young man through the Church of Scientology and two attended brother Connor's 17th birthday party together two weeks ago.

If and when Isabella decides to tie the knot -- with Eddie or with someone else -- do you think Nicole and Keith will attend, alongside Tom and Katie???

Here's some video of Keith arriving at LAX yesterday after he performed at the Grand Ole Opry, post vocal cord surgery ...

43-year-old Nicole Kidman overshadowed her Grammy-nominated hubby Keith Urban on the red carpet tonight at the Grammys ...

After mocking her ex, Tom Cruise, saying she could finally wear heels once they divorced, Nic's back to being the taller one of the couple!

Still, it seems like she's found true love in Keith with their new baby girl Faith and their 2-year-old daughter Sunday Rose.

And Kidman's on top right now with her film Just Go With It beating out Justin Bieber's Never Say Never this weekend at the box office. Congrats, Nicole!

I so hate to say it, but remember when Nicole Kidman made fun of her ex Tom Cruise on national television, saying she was happy to finally be able to wear heels and not tower over her husband? Ummm ...

Still, she and Keith Urban make a cute couple and they seem totally happy together. Guess Nic realized height isn't everything ...
