Siva was reportedly strolling through New York's west side district of Chelsea when he spotted a man beating up his partner, so he jumped into action.
Unfortunately, the British boy band star suffered a black eye in the incident but it he seems his intervention certainly saved the day, as it gave the woman a chance to escape.
According to Siva's rep, who spoke to TMZ, the Irish star is hoping the lady will get in touch with him to let him know she is ok.
What a guy!
Last month, Siva joined his Wanted bandmates for their last ever gig before their planned and unspecified "break". The band - Siva, Max George, Nathan Sykes, Jay McGuiness and Tom Parker - announced their decision to take a hiatus in January.
The lads performed at Fusion Festival in Birmingham, however Nathan was a no show as he had pre-exisiting work commitments in the US.
