Not Ready For Love? Eva Longoria sparks break-up rumours as she steps out solo with puffy eyes for goddaughter's birthday

Eva Longoria has been practically joined at the hip with new boyfriend Ernesto Arguello since taking their relationship public in early July.

The couple even holidayed together in Europe later that month, flaunting their love in Spain and romance capital Paris.

They are also said to have visited Nicaragua before announcing their change of status, where Eva was introduced to her 34-year-old beau's family for the first time.

Blooming lovely: 'Celebrating Gia's birthday with my girls,' Mario Lopez tweeted from his daughter's birthday bash of pregnant wife Courtney Mazza and pal Eva Longoria, who revealed puffy eyes under her shades

Pamper time: The busy actress stepped out solo as she treated herself to a relaxing manicure and pedicure in West Hollywood, California on Saturday, before heading to her goddaughter's party in Glendale

But with the actress's work commitments keeping her busy in recent weeks, the pair haven't been spotted together since returning from Marbella on August 6.

The bubbly brunette enjoyed another solo outing on Saturday, as she treated herself to a mani-pedi at Diamond Nails & Spa Tanning in West Hollywood, California before heading to a birthday party for her goddaughter Gia in Glendale that afternoon.

The star emerged from the salon clutching a cold bottle of water on the scorching summer's day, making sure to keep her eyes covered under trendy black and gold-rimmed glasses.

Ready for her close-up: The star wore very little make-up but looked perfectly flawless with her hair pulled back with a headband, keeping her eyes covered under large black and gold-rimmed glasses

Keeping cool: A pretty caramel and white striped maxi-dress with red belt and a bottle of ice-cold water was the order of the day as temperatures soared, while the star also carried her favourite white Coach bag

Evidence of her pampering session came in the form of orange complimentary disposable flip flops that she wore as she headed across the parking lot to her car.

The stunning star kept her long brown tresses pulled back from her face with a sweet Alice band despite wearing little to no make-up, though she looked picture-perfect regardless.

Calling Ernesto? The stunning brunette headed to the bash solo and left with friends, having not been seen with her boyfriend since returning from Spain on August 6

Perhaps adding to speculation that her relationship is faltering, the former Desperate Housewives actress retweeted a rather telling message on Friday.

'Sometimes the worst battle you have to fight is between what you know and what you feel.'
Not letting any possible romantic complications get her down, Eva made an enthusiastic appearance later that day at a birthday party for her goddaughter Gia - longtime pal Mario Lopez's daughter.
However, taking her sunglasses off for a photo with her friends, the twice-divorced star revealed puffy bags under her eyes that could be the result of some restless, tearful nights.

Two of a kind: Courtney and her lookalike daughter both donned pretty white outfits for the celebration, though the soon-to-be mom-of-two opted for a flowy tie-dye dress instead of a tutu

No doubt taking solace in the company of her close pals, the star pasted a beaming smile on her face as she fondly touched 31-year-old Courtney Mazza's burgeoning baby belly.
With the 39-year-old Extra host's wife due to give birth to the couple's second child in early September, the doting parents brought daughter Gia's birthday celebration forward - before things get too hectic.
Their tutu-wearing tot, who officially turns three on September 11, enjoyed a fun-filled day revelling in the pink princess-themed bash - even donning a cute bow atop her head for the occasion.
She could barely contain her excitement as she posed with her expectant parents in front of a huge cake decorated with Beauty And The Beast's Belle and Tangled heroine Rapunzel.

Birthday girl: Mario and wife Courtney Mazza's daughter, Gia, was thrilled with her pink princess-themed party, which was thrown early so as not to coincide with the birth of their second child in early September

Party too hard? Mario looked a little worse for wear as he carried an empty sangria container from the party, tweeting '#toomuchsangria'

After the party, Eva was spotted leaving Katsuya in Hollywood wearing a completely different outfit.
The Texas native mixed it up in a pretty printed blouse, white trousers and tan heels.
The petite brunette could be seen carefully making her way down some stairs as she held onto a leather clutch.
