No time to party! Kendra Wilkinson works on her birthday as she makes a guest appearance on Playboy Radio

It seems Kendra Wilkinson does not like taking a day off.

For the reality star celebrated her 28th birthday by making a guest appearance on a radio show in Miami Beach on Wednesday.

But it seemed she had made sure to come prepared to have some fun once the hard work of her interview spot next to a swimming pool was over.

For she was clearly wearing a turquoise bikini underneath an visually pleasing ensemble of a figure hugging white vest and tiny tight shorts.

Of course, the fact she was appearing on her friend Jessica Hall's show on Playboy Radio suggests it would not have been the most taxing of appearances.

Kendra of course has a long-standing relationship with the pornographic media empire, as she shot to fame one of mogul Hugh Hefner's three girlfriends, even starring in the E! reality television series The Girls Next Door which followed her life in the Playboy Mansion.

Not seen on Wednesday was her husband Hank Baskett and their three-year-old son Hank Jr.
The former NFL wide receiver, who now owns training center Athletic Gaines, was busy promoting the OverDog video game app at the E3 convention in Los Angeles.

Her 30-year-old beau made sure to tweet: 'Lil Hank & I want to wish you a very Happy Birthday baby!!! We love you & are blessed to call you wife & momma!!'

Kendra has been joined in Miami for a girls-only holiday by make-up artist Jo Jo McCarthy, Sons of Anarchy star Kristen Renton, and presenter Jessica Hall.

Yesterday she was spotted taking advantage of the Florida sunshine as she frollicked on the beach with her girlfriends in a revealing pink two piece swimsuit.
