Christina Milian pregnant rumors were proven to be false as the R&B singer displayed her slender body while doing some serious workout. Rapper Lil Wayne's rumored girlfriend, who now has her own reality series, was spotted with her sister Lizzy.

The 33-year-old singer showed some sweat while working out with her sister Lizzy at a park in Studio City, California.

The star, who has been dealing with Christina Milian pregnant rumors since last year, debunked the seemingly undying issue by rocking a fitted gym wear that showed off her body curves, The Daily Mail said in a report.

Showing that she is not pregnant with her rumored boyfriend Lil Wayne's baby, Christina Milian wore a skintight workout gear that included a pair of white tights and a matching vest emblazoned with a cloud print.

The mother-of-one completed her ensemble with a white, grey and pink Reebok trainers and a pair of large brown designer sunglasses to possibly protect her eyes.

Christina Milian and Lizzy were spotted doing seat ups, dips, and high knee running in place as they braved the heat of the Californian sun.

Christina Milian opted to tie her brunette hair in a messy bun while she decided to wear minimal make-up.

Meanwhile, her sister looked equally stylish and hot with her black and white patterned sports bra and matching full-length tights. She too displayed her toned abs.

This workout session of the sisters is set to air in the reality show "Christina Milian: Turned Up," which premiered last week, E! Online said in a report.

The "Dip It Low" singer has been bugged with pregnant rumors since Christina Milian and Lil Wayne were reported to be dating.

The pair sparked rumors that they are an item after they were seen on a series of public outing following their latest music collaboration.
