But it would seem she got a little too hot after a while in the full heat of the sun, and later tied her locks off her face as she continued the celebrations.
In spite of Tulisa appearing in full-on party spirit as she enjoyed her day out at Ocean Beach Club, she may have been feeling a little worse for wear upon her arrival, and was spotted carrying a bottle of what could have been a hangover remedy as she wandered into the club.

The star has certainly been making the most of her time on the White Isle, and has been spotted dining and partying in the resort of San Antonio on the north west coast of the island.
Her trip comes just a few weeks after ex-boyfriend, footballer Danny Simpson - who she split from in May following a six-month relationship - also hit Ibiza for a lads' holiday.
Tulisa's recent break comes after it was reported she is planning on starting a new life for herself in the US following her dramatic fall from grace last month.

A source told Closer magazine: ‘Tulisa says as soon as all this drama is over, she wants to move to Miami to start a new life. She loves it there and has friends there who say they will help her out.
‘She said she feels trapped and suffocated in England, she wants a new life in the US, where she hopes to establish herself as a solo artist.’
Last month, Tulisa attended a police station ‘by appointment’ after allegedly being caught fixing the sale of £800 of cocaine in an undercover sting by a national newspaper.

The troubled singer turned 25 on Saturday – a week after she flew out to the Balearic hotspot for a much needed holiday – and promptly celebrated by cracking open magnums of Laurent Perrier Rose during a day of sun and sand on the island’s Cala D’Hort.
Sporting a fifties style swimsuit with a garish, mottled ‘snake-print’ design, Tulisa squealed as she was squirted with champagne spray by a friend before raising the entire bottle to her lips.

Perhaps with that in mind, the former X Factor judge appeared to make a wish before throwing a pebble into the sea for luck.
Tulisa later stepped out with friends including actress Chelsea Healey for a night on the tiles as her birthday celebrations continued late into the evening.

She recently underwent a beauty makeover, and Tulisa Contostavlos was certainly looking mint on another day by the beach in Ibiza.
The singer wore a pale green bikini on day eight of her partying holiday, as she, Chelsee Healey and her friends enjoyed a boat ride and a dip in the blue waters of the Mediterranean.
The group headed to San Antonio to explore the rest of what the Balearic island has to offer.

Tulisa's bikini was a halterneck style but the strap could be detached to make it a a bandeau and reduce the amount of tan lines.
But it seems the former X Factor judge couldn't go too long without checking out her appearance, as she pulled out a handheld mirror while in the water
Maybe some salt and gone in her eye or her make-up was suffering under the conditions, either way, Tulisa wasn't going to let that affect her new exterior.

She was clearly taken with her new look, writing ‘Quick pose 4 @cathairine @russianlengths 2 flaunt me new locks wooooooooo.’
But since arriving in Ibiza, Tulisa seems to be still holding on to the 'Queen of the Chavs' title, as she has been stepping out in a few questionable outfits in the day and night.
Luckily the bog hoops and chains had been put away while the former N-Dubz star jumped in the waters on Friday, but it seemed to be a little chilly upon first touch, as she climbed carefully into the sea from her boat with a surprised look on her face.

Wearing a white dress with nude platforms and carrying a Chanel clutch bag, the birthday girl had ditched her previous night's chavvy look for a more chic outfit.
She instagrammed various photos throughout the night and shared a picture of her birthday card too, which showed that her nickname is 'TT'.

Posting photos on her Instagram, Tulisa wrote: 'Dinner at me favourite rezzy in Ibiza la casita! #buzzin best food In town, waited all week 4 this.'

On Wednesday night they partied at the Ibiza Rocks gig, where Tinie Tempah was performing.
On Monday, they checked out the famous sunset over San Antonio Bay at Cafe Mambo before moving on to the Plastik club.
