Nicole Murphy showcases her toned tummy in a sexy black and white bikini

She is the mother of five children.
But based on the stellar condition of Nicole Murphy's enviable abs, one would never guess.

Washboard abs: Nicole Murphy, 45, hit the Miami beach on Sunday in a bikini that revealed her toned tummy

The 45-year-old former wife of comedian Eddie Murphy hit the Miami, Florida, beach on Sunday in a flattering black and white bikini.

With daughter Zola, 13, at her side and friend Claudia Jordan, the trio enjoyed both sunning and splashing.
Nicole, a fitness fanatic, highlighted her trim curves in high-cut black bottoms and a contrasting white halter bikini top.

Taking advantage of the refreshing ocean, the pixie-cut ex-wife of Eddie Murphy was seen splashing around in the salt water, not limiting herself to the sandy beach.

After a quick dip the Hollywood Exes star crawled back on shore for a leisurely walk, taking a rest on a lounge chair.
And as she spent much of her time dipping into the clear Pacific Ocean, Nicole opted to spend the day make-up free.

Adding to her youthful essence, Nicole also wore a small silver-hooped belly ring.
Not spotted on the sand was Nicole's fiancé, former football player Michael Strahan who likely stayed back in New York City where he films his daytime talk show Live With Kelly And Michael.
Michael and Nicole have been engaged since 2009, when he proposed at Disneyland.
Strahan, who is twice divorced and has four children, retired from the NFL in 2008 after playing his last game in a victorious Super Bowl.
