The X Factor judge has endured a difficult few weeks after falling ill and having to miss part of the X Factor finale and then being faced with claims that Stephen had been abusive towards her.
Mel and Stephen have both vehemently denied this.
And, showing all is fine in their world, the couple posed for a photograph together with pals on New Year's Eve. It was uploaded to Stephen's Twitter account alongside the message: "Nye 2015 with my baby @officialmelb and one of my best buddies and his lovely wife!! #bigdogstatus."
Mel, meanwhile, appears to be embracing the New Year with positivity, posting a motivational message for fans on New Year's Day.
She said: "Stand proud in the skin your in no matter what people think or say about you!! Make 2015 count yippppeee."
Mel also retweeted a message from former Spice Girls bandmate Geri Halliwell who thanked fans for all their support of the Spice Girls, both as a group and individuals, over the past twelve months.
Mel added on Instagram: "Boo I see you ALL I have the best fans #lovemyfans."
No doubt Mel and Stephen are looking forward to a fresh start in 2015 following a tricky month which saw their marriage dominate the headlines both here and overseas.
It all started when Mel was forced to pull out of a press conference and the first night of the X Factor finale through illness. Then, when she returned for night two, fans claimed to see bruising on her face, which sparked rumours that Stephen had hit her.
Stephen was quick to deny the "disgusting" and "untrue" rumours, saying he would never do such a thing.
"I don't usually respond to Twitter messages but I will respond to comments of hitting my wife which I think are quite disgusting and untrue!" he said. "Mel was very ill. A bunch of doctors helped her get better. If fans can't just relax before being negative they are not real fans of Mel."
"I love my wife, I care about my wife. I'd take a bullet for her," he later said.
Mel also dismissed the speculation, telling fans: "I'm very good was very polly [sic] but much better now and for the record my hubby never would lay a hand on me sorry took so long but any response fuels rumours #lovemyfamily #lovemyfans."
