Nicole Scherzinger looked like she may have a little too much to drink after partying the night away with friends in London's nightclub the Project, Tuesday night. The singer was photographed giggling to herself and she reportedly also took a tumble when she left the venue the following day.

Mail Online shared several photos of Scherzinger leaving the Project at 3:30 a.m. accompanied by her entourage. She reportedly stumbled on her way out of the club and is even seen holding on to her male companion's hand for support.

The 37-year-old was also photographed with her hand on her mouth as she appears to giggle at something. Another photo shows the Pussycat Dolls singer seemingly in a daze as she walks by herself. According to Mail Online, after a night at the Project she and some friends headed to a local food joint.

Before hitting the Project, she tried out Mayfair's new hotspot Sexy Fish, where she was spotted still in good spirits. The former "X-Factor UK" judge was photographed walking out of the venue unassisted.

Scherzinger's fun night out in the British capital came after it was reported that she and tennis player Grigor Dimitrov, 24, are dating. A source told The Sun that they have been secretly seeing each other since Dimitrov broke up with Maria Sharapova in July.

Despite the age difference, the source claimed both are "completely besotted with each other." They have reportedly successfully concealed their romance for the past months since they have been "careful not to be pictured together because they don't want the pressure of the relationship being in the public eye."

Before his relationship with Sharapova, Dimitrov was also rumored to have dated Serena Williams. Scherzinger, on the other hand, was in a long-term relationship with Formula One racer Lewis Hamilton. They broke up after seven years of being together.

However, back in November Scherzinger admitted during an interview on the ITV show "This Morning" that she is still single. She also insisted that she is not seeing anyone, when show host Peter Schofield directly asked about her dating status.

Meanwhile, Scherzinger's ex-boyfriend has since been linked to different women after their split. Lewis was once rumored to be dating Victoria's Secret model Kendall Jenner and "Diamonds" singer Rihanna. However, he had since denied being in a romantic relationship with either of the girls and only referred to them as his good friends.
