Ex-One Direction singer Niall Horan reignited romance rumours with model Jessica Serfaty after the two were spotted enjoying an intimate outing in Los Angeles on Monday. Their night out comes right after the Irish heartthrob sang to a star-studded crowd including ex-fling Selena Gomez during the 2016 AMAs with his rendition of This Town.

According to a report by the Daily Mail, the on-again, off-again pair appeared to be in high spirits as they stepped out for a low-key outing at The Troubadour.

For the occasion, the boy-band singer dressed in a casual full-sleeve olive green tee and teamed it with a pair of dark denims. He also sported a flat cap in the classic colour in an attempt to keep his outing low.

On the other hand, Horan's rumoured love interest donned ripped jeans and an over-sized jumper in bright red. Keeping her shoulder-length blonde locks open, Serfaty channelled some major rock and roll vibe with a dash of bling in the form of her choker and chain.

The pair was headed to watch a gig by Gavin James, who is one of Horan's friends. Sharing details about their night together, the former America's Next Top Model contestant even posted a tweet, saying, "Music kinda night".

Serfaty was linked to the 23-year-old singer earlier in March and the two even stirred some controversy following their display of love. When news of their alleged romance surfaced, the model's ex-husband, Ididia Serfaty, apparently criticised her for ignoring their son Roman.

However, before the One Thing crooner was spotted with his rumoured lady love, he made headlines for his sweet reunion with alleged ex-fling Gomez during the AMAs. The awards night was all the more special for the songstress because of her comeback and the moving speech addressing her struggles.

Later, Horan sent a shout out to Gomez with a sweet message on Twitter, "Just watching the show back from last night . Really great show . Loved it . love to Selena for the speech , brave young woman," he wrote.
