They believe they can fly! Gwen Stefani and son Kingston, nearly 5, were spotted as they made their way through Heathrow Airport in London on Thursday (May 12).

Gwen, stylish as usual, had on a pair of beautiful shiny leather riding boots. Kingston was traveling light, carrying only his stuffed dog.

Gwen and the rest of her family – husband Gavin Rossdale and son Zuma, 2 – have been spending time relaxing and visiting relatives in London the past week. They also hung out with celebrity friends Gwyneth Paltrow and Chris Martin.

So long, Rihanna...

There's a new girl on our founding editor's "Top Five hotties" list..although it's not the youthful upgrade that many of our fans may have been hoping for.

Gwen Stefani, 41, joins actresses Charlize Theron (35), Angelina Jolie (35), Halle Berry (44) and Salma Hayek (44) on Sic Willie's list. Oh, and before anybody starts slamming him for his obvious "Mothers I'd Like to Fahrvergnugen" fetish - Stefani was recently selected as the new cover girl for L'Oreal Paris.

Not too shabby for a mother of two...

And while promising to keep his eyes peeled for "younger women... at least on the internet," Sic said he wasn't going to be dissuaded from following his own definition of "hot."

"Contrary to the porn peddler pronouncements of some of my critics I am into beauty that transcends trends and styles," Sic said. "That's what I find 'hot,' and that's not something you're ever going to get from the latest inflatable princess or the fresh-faced teeny-bopper of the week. Like Madonna before her, Gwennie has that transcendent translucence that's every bit at home on the cover of Vogue as it is on the mirror of a dirty bathroom in a punk rock club."

Plus, she "ain't no hollaback girl."

Not many moms could pull off this sheer top, but Gwen Stefani isn't like most moms.

The No Doubt rocker has been in London for the past several days with her family playing in the park and taking springtime strolls, but she was spotted on Tuesday afternoon wearing this very see-through top. The look was topped off with a navy blazer, blue slacks and of course, her signature red lips.

Her 4-year-old Kingston was also with her, and by the looks of it, he's gotten really comfortable with the cameras being around.

As the paps snapped him digging for some gold! Got to love little kids.

With it's high hills and breathtaking views of London, Primrose Hill is the perfect spot for a family to spend a relaxing Sunday afternoon flying kites and kicking a ball around.

And that is exactly what Gwen Stefani and her brood did today.

The rockstar family didn't let the grey clouds dampen their spirits as they make the most of their stay in Gwen's husband Gavin Rossdale's home town.

Gwen, 41, and Gavin, 45, were all smiles as they strolled into the park with their two-year-old son Zuma.

Eldest son Kingston, five, was nowhere in sight - perhaps he stayed over at Gwyneth Paltrow's house after their playdate with Gwyneth's children Apple and Moses.

Gwen was rocking her usual quirky style in a colourful leather jacket, black harem trousers and knee-high riding boots.

Bush frontman Gavin was more casually dressed in a jeans and a flannel shirt. Gavin looked like he was having a great time showing little Zuma how to fly a kite.

The wind at the top of Primrose Hill will have been ideal conditions for kite flying, but Gwen lay back and let the boys do the running during the family outing, preferring to recline in the grass.

She watched as Gavin instructed little Zuma on how to fly the colourful kite properly and later cuddled the cute tot as he played with her sunglasses.

The family have become a fixture around exclusive Primrose Hill in recent weeks, and have been spotted shopping and enjoying the local cafes and pubs.

They jetted into London last weekend and have been catching up with friends including Gwyneth Paltrow and relatives of Gavin, who was raised in Kilburn.

Fashion designer Gwen, who has also just been named as a new face for L'Oreal Paris, and husband Gavin, have also just been unveiled as one of the world's Top 20 hottest couples by website Zimbio.

They married in 2002 after getting together in 1996. Gwen said of their relationship last month: 'It's unbelievable that we've been able to stay together. I feel so proud of us. It's one of my biggest achievements.'
