NEW YORK Robin Thicke has been out plugging his new album “Paula”. However one publicity stunt didn’t go quite the way his PR people hoped it would. VH-1 hosted a live Twitter Q&A with the singer but #AskThicke backfired in a big way. The session mostly generated criticism for Robin, his music and especially his treatment of estranged wife Paula Patton – who he admits he hasn’t seen in over four months. It wasn’t all bad though; Robin did encounter a few admirers outside the studio. Elsewhere in New York, Kelly Osbourne showed off her purple Mohawk and brand new scalp tattoo while doing the morning show rounds. The fashion host tweeted and posted to her Instagram while getting inked and revealed her mom Sharon is not a fan of the look. LONDON Over in London, A-listers mingled with royalty at The Serpentine Gallery Summer Party. Among the high profile guests were Princesses Beatrice and Eugenie along with Orlando Bloom, Pharell Williams, Bradley Cooper and girlfriend Suki Waterhouse, Dougray Scott, Gemma Arterton and Keira Knightley – who brought along hubby James Righton. We recently caught up with Keira to find out about her new romantic comedy “Begin Again”. :31 Keira Knightley: I loved the reality…up :41
