Gwen Stefani

Gwen Stefani paired a black-and-white polka-dot sweater with her signature red lipstick for a stylish outing in LA yesterday. She's been enjoying downtime with family after wrapping up her tour with No Doubt at the end of last month. Gwen's also been sure to sneak in romantic time with husband Gavin Rossdale, who recently finished his own world tour with Bush. Last week, Gwen and Gavin had a couple's day while shopping around LA together. The pair are getting back to their regular routine after spending the holiday season with Gavin's family in London, and their boys are back on schedule as well — Gwen ran errands with Zuma and Kingston by her side last week.

Gwen Stefani and Gavin Rossdale went shopping together yesterday in Beverly Hills, CA. They're getting reacquainted with their home base of LA following an extended holiday getaway to Gavin's native England. Gwen, Gavin, and their sons, Kingston and Zuma, spent much of December and early January in London, where they visited with Rossdale relatives, including their half-sister, Daisy Lowe. Now that they're in the US, Gwen's focusing on her work with No Doubt. Gwen flaunted her abs during a performance last week on Jimmy Kimmel Live. She also tweeted, "Song writing, listing to The Cure," hinting that more No Doubt — or Gwen solo material — is on the way.

Gwen Stefani took her youngest son, Zuma Rossdale, out in LA yesterday morning. Zuma wore a Spider-Man sweatshirt and let his mom give him a lift on the way to class. Later in the day, Gwen switched gears to take her oldest, Kingston Rossdale, to do some biking in Griffith Park.

The No Doubt singer has spent a hectic Fall and Winter promoting the band's new album, Push and Shove. No Doubt performed on Jimmy Kimmel Live! just last week, but Gwen did take a break from her duties with the band over the holidays, spending time in London with Zuma, Kingston, and Gavin Rossdale. Gavin's adult daughter from a previous relationship, Daisy Lowe, also joined the family for a stroll in the city the day after Christmas.

Gwen Stefani hit the stage for a performance of "Looking Hot" on Jimmy Kimmel Live! in LA last night. She flashed her abs during the show, which was Jimmy's first in his new time slot and also featured an interview with Jennifer Aniston. No Doubt got together to rehearse for the spot on Sunday, after Gwen and her family returned to the West Coast after their stay in London. The Stefani-Rossdales celebrated the holidays in Gavin Rossdale's hometown after wrapping up a busy 2012 that included the release of No Doubt's sixth album and Gavin's world tour with Bush. Now Gwen and Gavin are getting back to their LA routine and were spotted grabbing coffee together on Monday.

Gwen Stefani and Gavin Rossdale held hands for a walk around London with their two sons, Kingston and Zuma, yesterday. Gwen, Gavin, Kingston, and Zuma then headed to the airport together to catch a flight out of town this morning. The Stefani-Rossdale crew has been spending quality time together since last month. The foursome typically spends the Winter holidays with their extended Rossdale relatives, including Zuma and Kingston's half-sister, Daisy Lowe, in England.

The trip brought some much-appreciated downtime for the rocker parents, who are coming off of a busy 2012. Gwen released a new album with No Doubt and Gavin traveled around the world with Bush. Gwen also graces the cover of this month's Vogue and, inside the publication, talked about marriage with Gavin. She said of their life together, "It is the ultimate collaboration. Both of us have such strong opinions about how it should be, and it's really fun to do it together."

Gwen Stefani took a stroll with her guys Gavin, Kingston, and Zuma Rossdale through London's Primrose Hill on Sunday. The foursome met up with Gavin's daughter, Daisy Lowe, who was spending the afternoon with her pup Monty. The Stefani-Rossdale clan generally spends Thanksgiving in LA with Gwen's relatives and then travels to the UK, where they celebrate Christmas with Gavin's side of the family. Gwen and Gavin are winding down another successful and eventful year. Gwen released a new album with No Doubt, and Gavin traveled the globe with Bush, all while coparenting Zuma and Kingston. Gwen ranks among the most stylish moms of 2012, and it seems she's planning to take that title into the new year, as she recently landed the January 2013 cover of Vogue.

We spotted many well-dressed celebrities this week, but there were a handful of starlets who were extra inspiring. Gwen Stefani styled a sleek and sophisticated red leather look in Studio City, Jessica Alba's off-duty LA ensemble proved a pop of color is always fabulous, and Ali Larter worked an edgy-sweet combo perfect for any occasion while shopping in West Hollywood.
