Showing her best side: Actress Kate Beckinsale relaxes in a black bikini on a sun lounger in Mexico with husband Len Wiseman yesterday
English actress Kate Beckinsale is fast approaching 40.

Killer figure: The 38-year-old put on a show for her other half as she stood up to fasten her hair into a bun
Kate, 38, put her stunning figure on show in a black bikini while lapping up the sunshine in Mexico with her husband Len Wiseman.
Lucky Len was treated to an impromptu poolside performance from Kate as she stood up to fix her long brunette locks into a tight bun.
And he was apparently quite enamoured by the view as he happily took snaps of his wife on his phone.
Snap happy: Len appeared to be enjoying the view and took pictures of his wife on his mobile phone
Strike a pose: The Underworld star points at Wiseman as he lounges on the sunbed in his swim shorts
The couple, who met on the set of Underworld, then enjoyed smooching together on the sun loungers.
Kate climbed on top of Len, showering him with kisses, as he willingly reciprocated with a hands-on approach.
Beckinsale relocated to Los Angeles in 2003 with Wiseman, before marrying him the following year.
