Hot model mom Miranda Kerr may have some competition in 2012 — with the recent news of Lily Aldridge's pregnancy, we're excited to see what kind of spin the edgy-cool catwalker puts on maternity wear. Lily is known for her ability to seamlessly transition between sex kitten (have you seen her on the Victoria's Secret runway?) and effortless street style queen, not to mention her perfectly tousled ombré waves. Being married to Kings of Leon frontman Caleb Followill certainly plays a part in Lily's rocker-chic look — the model has mixing and matching down to a science, and keeps us captivated with an arsenal of leather jackets and skinny pants, curve-hugging dresses, and slouchy tees. Click through to see 10 reasons that Lily Aldridge is our latest street style crush.

We all have favorite pieces in our wardrobe, and to this point, Rosie Huntington-Whiteley would definitely agree. We've spotted the model actress in a rotating collection of low, slouchy, neutral booties that amp up her casual daytime skinny jeans and leather jacket pairings. It's pretty clear that her bohemian, laid-back style has been given a boost of cool with help from her chic Isabel Marant, Zadig & Voltaire, and Barbara Bui neutral-hued footwear. For proof of Rosie's major bootie moments, just click through, and then find your own perfect pair.

We're just a month away from adding affordable Jason Wu to our wardrobes with the launch of the designer's Target collaboration — that is, if we can get a piece before it hits eBay. At first we could only speculate what it might look like — we suspected Wu's signature femme with girly accents and quintessential charm. Now we're treated to a first look that delivers those essential elements with Peter Pan collars, sweet knits, and ladylike handbags. Click on for the first images of the limited-edition collection and a peek at Wu's Target campaign — then mark your calendars for Feb. 5 and prepare for the shopping mayhem.

Well, the holidays are over, and a brand new year is upon us.

We've rounded up 10 pretty postholiday pieces that are sure to bring you into the new year in style. Click through to see and shop them all.
