The pop superstar, 27, has not been pictured with Taylor since August and rumours were circulating that the couple have been drifting apart for some time - especially as Gaga has been extra busy promoting her new album ARTPOP over the last few months.
According to The Sun, 32-year-old actor Taylor had enough and ended things with the songstress this month, claiming that she is "married to her job".
A source told the newspaper: "He loves the cool, down-to-earth girl but hardly gets to see her. Gaga never stops working..."
However, despite reports that the couple had split, Taylor was then apparently seen supporting Gaga at the YouTube Music Awards last night (3 November).
The pop singer performed her new single 'Dope' with Taylor supposedly hanging out in the building. He was later seen signing autographs and posing for pictures with fans outside.
Gaga has been caught up with her work life a lot more lately, touring the UK and the US on a promotional trip for ARTPOP.
Her tour has so far seen her performing at the MTV VMAs in August and treating fans to a risqué show last weekend on The X Factor, where she also settled her feud with judge Sharon Osbourne.
She has been dating boyfriend Taylor for two years and the couple were even rumoured to have made plans to marry later this year, although this was not confirmed by either star.
In the early stages of their relationship, Taylor appeared in Gaga's music video for her hit single 'You & I', which included some steamy scenes between the two - proving that they're definitely a passionate match for one another!
Could the pair still be trying to work things out or is their relationship coming to an end? We're totally confused!
