Justin's A-list birthday bash

Behind the scenes at Justin Timberlake's surprise 28th birthday party

Aww. Jessica Biel is not only a super-hot girlfriend, she’s super-thoughtful, too.

The actress threw beau Justin Timberlake a Super Bowl-themed surprise birthday party this weekend to celebrate him turning the grand old age 28.

The stunning star hired out Roosevelt Hotel’s exclusive penthouse suite for the Super Bowl-style shindig, which saw 100 friends and family feasting on treats like gourmet buffalo wings, pizza, and red velvet cupcakes.

Guests included both sets of parents, Biel’s brothers, Timberlake’s cousins and his best buddy, Trace Alaya.

Biel planned the party single-handedly, and even worked the room as a host, dressed in a little black cotton dress and flats.

One insider said: ‘They held hands and relaxed. They seemed very happy together.’

Well, if the acting career goes down the pan, at least Biel knows she’ll cut it as the perfect party-planner.
