This week we've seen a few transformations and celebrity hair style trends worth talking about. Alicia Keys Singer and actress Alicia Keys has been queen of the makeover in recent years and she has debuted yet another key style change. Her hair has been in braids, worn long, short and even shaved in the past, but this time its seems as though she has gone for a bit of everything! With an undercut and her long hair swept over to one side with signature mermaid waves and partly braided locks, the new look is contemporary and cool. The new hairstyle was first spotted in New York while Alicia was working on filming a TV commercial. Later she was spotted buying kids books from a market stall - she recently had her second son in December last year. Alicia recently admitted not being happy with her post baby body, although she already looks fantastic to us! Jennifer Lopez Jennifer Lopez arrived at LAX airport last week showing off a new cut, a stunning brunette bob. The new style gives a more relaxed and casual feel than the waist length and straight locks we've seen previously. The shoulder skimming haircut is the perfect look for summer 2015 and the shorter length is perfect for the hotter temperatures. The bob is still right on trend with Jessica Alba and Sarah Hyland also recently getting the chop. Colour When it comes to the hot colours of the moment it seems like the pink hair trend still has a lot of life left in it yet. Madonna, Hilary Duff and Nicole Ritchie are all showing off various shades, of pink from subtle to full on. Singer Natasha Bedingfield also took her already pink locks a step further this week by going for the full on cotton candy look.
